Query Loop Taxonomy Logic AND OR

Hello!
I think the Query Loop Block is fantastic!
What I am trying to do is: display posts from a custom post type via categories, BUT I need to have a “AND” logic for the chosen categories. As I understand it, the categories work with an “OR” operator, so the posts displayed can be labeled with “Category A” OR “Category B”. I would need to display the posts labeled with “Category A” AND “Category B”.
Is this achievable with the Query Loop Block? Because I need a solution my clients could work with independently.

Thank you,
Angie
