How to manage roles which are defined by multiple values

Hello,
In the desktop version you can manage roles by defining a name, choosing the table and the "column"
Then you select one value out of this column to define a role
How can you manage a role which is assigned to more than one value out of one column?

Example:

There might be a role 1 allowed to see region North

There might be a role 2 allowed to see region South

There might be a role 3 allowed to see region North, South, ...

How can I modify the term (role1) below so that it fits to role 3, which is allowed to see at least 10 regions out of 30 regions

[Region] = "North" ...???

Thank you
