How to test the existence of a property in a custom query in a custom property on a device in Logicmonitor?

As far as I recall, you cannot define a dynamic group using inherited properties.  We have had to do contortions to get around that restriction as well.  You might be forced to create a propertysource that assigns auto.XX properties and then use that to define the dynamic group.  I am not sure why this restriction exists, never have received a satisfactory answer.

You cannot use inherited properties for dynamic grouping. The reason for this is that an inherited property could cause a device to go into a group, which might change the inherited property (because now it's inheriting from a new additional group). This could cause the device to no longer match, causing it to be removed from the group. The removal would reset the property to its original state that matches the dynamic group rule, causing it to be added back in, causing it to inherit the property that removes it from the group. You get an infinite loop of adding then removing from the group.
