more flexibility in article permissions: be able to set visibility only if user is part of group A AND B (not it's an OR condition)

A user case

• User 1 is part of company A and using product C
• User 2 is part of company B and using product C

User of company A, B and users of product C are three different viewer groups

Permission for articles regarding product C is set to viewer group C but some should be seen only by company A and some by company B

If we could set the condition that a user must be part of both A and C that would solve the problem.

I'm open to alternatives.
