Virtualization

How do you deploy Add-ins to Users when MS Office 2010 is virtualized using Connection Groups (CG). Below is an example where different Users need different add-ins with Virtualized MS Office  

User A is a member of CG A which has MS Office and Add-in A

User B is a member of CG B which has MS Office and Add-in B

 And both work as they should.

However User C requires access to MS Office  and both Add-in A and Add-in B

 How do we achieve this as CG A is one virtual environment and CG B is another Virtual environment and therefore can't see each other ?

The only solution I can see is creating another CG with both add-ins and MS Office

e.g

User C is a member of CG C which has MS Office, Add-in A and Add-in B

However in a real environments different users requiring access to different Add-ins could become messy. but is this the solution ?

Thanks
