Assign Multiple Products to a Test Container

[RavenArens]

Is there any possibility of having more than one product assigned to a test container in SILK Central?  If I have Product A and Product B (each independent products but can optionally be used together) with tests associated specifically with those products, I can have each product assigned to its respective test container.  When I am performing system level testing, I also need to test the interaction of Product A with Product B.  

For reporting purposes I would love to be able to assign multiple products rather than managing other product Versions and Builds as platforms or configurations or some kind of combined product number.  If I could assign multiple products, I could then create reports that searches for test results based on product number and not have to review/search/manage configuration or platform information.

Is there any way of doing this?  Or a different approach to achieve this goal?

I have seen some suggestions in other posts that suggest creating a part number that encompasses what would be a stack of products but we have 40+ independent products that can be mixed and match with each other. I'm still looking for a better approach to system testing and identification of versions and builds tested against.
