Multi-input dependent dropdowns

Is it possible to have multiple selections from an EnumList be the input to a dependent dropdown?

I looked at Dependent Dropdown | AppSheet Help Center as a guide, so if I have 3 selections in my 1st dropdown, can I then return a filtered list of values in a dependent dropdown?

Use case:
User selects values EMEA, APAC from a region table from a list of values, EMEA, APAC, NORAM, LATAM.
I want to display all countries in EMEA and APAC region for a user to select a subset of these countries.
