ways to add a bunch of servers in SolarWinds

I'm trying to add a bunch of servers using Network Sonar Wizard. The SolarWinds Engineer informed me that I should need to minimize all SNMPs (SNMP retires, SNMP timeout, Search timeout) in order to use the WMI method. However, the results are still using the SNMP polling method.

Any other workaround to add the group of servers using WMI? Thank you.
