SNMP trap to NPM alert

OK, I've poured over the threads available here at thwack that explain different methods to trigger and alert and clear that alert when corresponding trap comes in.  I have an example that is slightly different from others I've seen here, I'd like to get some help with.

Scenario - another monitoring tool (HP BSM) sends a trap as an action when an alert condition is raised:

11/29/2016 8:08:20 AM    10.10.10.10     pwbsmdps02     public     SNMPv2-SMI:enterprises.5233.4.0.1     snmpTrapEnterprise = SNMPv2-SMI:e​nterprises.5​233.4

experimental.1057.1.0 = 10.10.10.10

sysUpTime = 226 days 5 hours 16 minutes 34.05 seconds

snmpTrapOID = SNMPv2-SMI:e​nterprises.5​233.4.0.1

enterprises.5233.4.10 = Business Transactio​n Flow:LMS;t​ransaction:L​MS_003_Aut​h;

enterprises.5233.4.9 = d4aec8817e​c54e330fcc​047bac0890​ea

enterprises.5233.4.8 = N/A

enterprises.5233.4.7 = Response time for 2 out of 3 transactio​ns was greater than 8.00 seconds.;

enterprises.5233.4.6 = For Business Transactio​n Flow "LMS", transactio​n "LMS_003_A​uth". Response time for 2 out of 3 transactio​ns greater than 8.00 seconds.;

enterprises.5233.4.5 = Major

enterprises.5233.4.4 = 33dcb5b068​c72fdb8779​050b29df5c​2c

enterprises.5233.4.3 = Regular Alert

enterprises.5233.4.2 = ITO: LMS Performanc​e Alerts

enterprises.5233.4.1 = LMS

It also will send a corresponding clear trap when the alert clears:

1/29/2016 8:29:38 AM    10.10.10.10     pwbsmdps02     public     SNMPv2-SMI:enterprises.5233.4.0.1     snmpTrapEnterprise = SNMPv2-SMI:e​nterprises.5​233.4

experimental.1057.1.0 = 10.10.10.10

sysUpTime = 226 days 5 hours 16 minutes 34.05 seconds

snmpTrapOID = SNMPv2-SMI:e​nterprises.5​233.4.0.1

enterprises.5233.4.10 = Business Transactio​n Flow:LMS;t​ransaction:L​MS_003_Aut​h;

enterprises.5233.4.9 = d4aec8817e​c54e330fcc​047bac0890​ea

enterprises.5233.4.8 = N/A

enterprises.5233.4.7 = Response time for 1 out of 3 transactio​ns was greater than 8.00 seconds.;

enterprises.5233.4.6 = For Business Transactio​n Flow "LMS", transactio​n "LMS_003_A​uth". Response time for 2 out of 3 transactio​ns greater than 8.00 seconds.;

enterprises.5233.4.5 = Informatio​nal

enterprises.5233.4.4 = 33dcb5b068​c72fdb8779​050b29df5c​2c

enterprises.5233.4.3 = Follow Up Alert

enterprises.5233.4.2 = ITO: LMS Performanc​e Alerts

enterprises.5233.4.1 = LMS

The traps always come from the same IP/Hostname: 10.10.10.10/pwbsmdps02

So in following other examples here, I created two rules in the trap viewer:

BSM Alert:

BSM Clear:

Note: ${vbData4} contains the unique alert identifier, which is why I chose it to correlate the events.  I verified in the Trap Viewer that new traps are colored properly.

Next, I created an new Alert in NPM:

Trigger:

Reset:

Now here is where I am stuck...  I would like to pull this varbind from the specific trap and put it into the Message displayed when this alert is triggered:

enterprises.5233.4.6 = For Business Transactio​n Flow "LMS", transactio​n "LMS_003_A​uth". Response time for 2 out of 3 transactio​ns greater than 8.00 seconds.;

Is this even possible?!
