Promotion Category Relationship Logic

[clarknelson]

When I am creating a promotion, I can select categories for which the discount will apply. I can select multiple categories, and it will apply to all products that have one of those categories. I believe this means that the query is using an "or" relational query https://craftcms.com/docs/3.x/relations.html#terminology

But what if I want to apply the discount to products that have both category A and category B? Using an "and" relationship? I see there is a drop down to select the source target relationship. Can we add a drop down to select "and" / "or"?

Thank you :)
