Perhaps use aliases ?

Or perhaps this thread could help to (apparently the opposite of your problem but some good info):

Hi MadGrb, 

I think you need to play with the Required Children feature. It will allow you to specify children objects that must be on window 1 and window 2. This will help you map these windows for sure. Please refer to the following article for more information:

Hi again,

Perhaps, the extended search will work:
