Help! 1 Property In 2 Property Groups?

how do I solve the following problem:
A property e.g. "Material" can be valid in the groups "Men" and "Women" at the same time - but you can only add 1 group to each property.
How can I solve the problem?
Thanks & Greetings Dirk

Sorry for my english. unfortunately not so good :(

I'm assuming you mean Feature. I'd suggest you review your features and possibly structure it like:


+ men

+ some material

+ women

+ some other material

where 'Materials" is the feature group. Or possibly


+ mens materials1

+ mens materials2

+ women's material1
