grouping objects from different layer

Hi,

I'm trying to find a solution for the problem below. I've read forums for hours without success... I would need two things:
1) group some objects for moving and scaling together, let's say object A and B is grouped into G1, C and D into G2.
2) view and print only specific objects of the group, let's say I need view/print only A and C.
I tried to solve it by placing A and C to Layer1 and B and D on Layer2. But when I grouped A and B it (re)places both of them onto one layer.


Does anyone know a way doing 1) and 2) together?


Thanks in advance,
