Subassambly configuration in assembly configuration

Hi everybody,

I have main assembly (I will call it A), in that assambly I have 5 subassemblies (B1, B2, B3 ... and so on). And in every one of those subassemblies I have 5 piping routes. I need to have a configuration in main assembly (A) with and without couplers (which are components of the piping routing). When I try to supress them from main assembly couplers are supressed in every config. in that main assy. How can I make a configuration in main assembly (A) that has supressed couplers from piping routing.

I have also tried to make a configuration in C level (piping routing) with suppresed couplers, but when i choose suppresed configuration of that routing in main assembly it is also suppresed in every configuration in main assy.

I am using Solidworks 2013 SP 4.

Thanks to everyone
