IPAM 4.6 Subnet Scan Frequency

Hi All

Upgraded to IPAM 4.6 recently and noticed that the option to set the amount of Subnet Scans at one time is no longer available. Is there a new place to set this?  Also, I have set the Scan Times for each DHCP Server subnets to every 18 hours and noticed that all subnets are scanning every 4 hours. I would rather not change each subnet (~3K), can this be done in the DB?

Assistance please.
