Multiple collections - which collection properties win?

Hi,

In short: if a device is in multiple collections, which collections properties win?

More info, I have 2 collections:

• 1 contains a config baseline (and therein config items) - Membership is to the 'All Mobile Devices' built-in collection
• 1 contains 10 apps - Membership is to query all Windows Mobile devices

The membership works fine. If I change the properties of either of the collections, such as Power Management which I want to select "Never Apply Power Mgmt...", does either take priority and if so how, or do both need it? How can I tell?

I'm trying to do the above but having inconcistent results, hence the q.

Thanks,

Piers
