NetPath Alert Trigger based on Latency/Packet Loss

Hello - I'm trying to setup an alert for NetPath that will trigger an alert based on a condition where the Latency and/or Packet Loss % history is over a certain value for a certain amount of time.   I've tried various ways with alerting on NetPath Probe, NetPath Endpoint Service and Endpoint Service on Probe.   I am just not seeing any conditions related to latency or packet loss from which to choose from.   Is this not possible or am I just missing something basic?   Thanks in advance!
