I don't quite understand this question. Do you want 'stage-locate' to be 
dynamically computed? No, that's no possible:

Again, you can use conditional requirements. To avoid duplicating those 
requirements everywhere, you can either use project requirements, or new main 
target rule 'my-stage' that does that:
