No OR Filter for Views with a Related Modules Criteria

No OR Filter for Views with a Related Modules Criteria

We would like to create a Deal View where the User can see all their deals.
For that, we would need an OR to connect the criteria. 

One of the Fields is a "multiselect User", these (Related Modules Criteria) can only be Filter with an AND.
Even between the "Related Modules Criteria" can only be AND connections.

Is there a reason for this limitation?
Is there another way to do this without an extra view just for that field?

Here is a screenshot for reference:
