GL Approval Workflow Rule for Specific Set of Users?

Summary:

Is there a way to build a rule which is focused on a specific set of users so that if they input a GL journal it goes to the team's manager first to be approved and then goes into the organisations standard rules which look at journal value and categories.

I see approval groups but is their a similar functionality for specifying a list of users who a rules should work upon? Is the expectation that you just create another rule and hard code the set of users IDs in to the rule and state the approver? Not ideal as people moving in/out of this team becomes a change request.
