Load project budgets and insert named resource as a planning resource

Summary:

We are using EPM to generate our project budgets. Our budgets are planned on named persons (from HCM).

However these named resources are constantly changed due to new hires and retires.

Is it possible to add a planning resource dynamically when importing the budget?

As I see the RBS, then we must add the resource on project specific RBS. If we had the option to update the central RBS and then push it out on all relevant projects, that would also work for us. But that is to my understanding not an option.

Any hints?
