Analysis authorization Union problem

Hello Experts,

We have very bad problem in our project and I hope that you can advise me how can be solved.

We want User "A" to be authorized to see certain values for Query 1 and other values in Query 2 for GL Account characteristics. We made two analysis authorizations with the restrictions for the queries, but the system makes an union between them and the User A has access to all of the combinations.

Can you give me some hints how to solve this problem.
