Creating multiple CUP initiators with the same role (sharing roles)

Question

Has anyone built a CUP workflow where roles are shared across different workflows/paths/initiators?
We have a situation where the users have several roles that are in multiple SAP applications and they want the requests for these roles to go down different workflows based on which application they were requested for.
For example, if role A is requested for application X1, the request should go down workflow A1.  But if the role is requested for application Z1, the request should go down workflow B1 instead.
I've tried using two initiators that have both role and application (role A AND application X1, role A AND application Z1).  This works fine as long as only one application/role is put in per request.  It sends it down the appropriate workflow, A1 or B1, based on the application and role.
However, if I try to build a request with two entries, one for each role/application combination, I get that "multiple initiators" error message.
I guess technically multiple initiators are found for the request overall, but each role/application has it's own path.  It should break this request into two parallel requests, one for each path.
Thanks.
P.S.  We are on GRC 5.3 SP 11.2.

Answer 1

So we've run into two CUP restrictions:
1.  If you want to allow a request to have entries that can split into multiple parallel workflows, you have to use the role names in your initiators.
2.  If you use role names in your initiators, you can't have the same role name in more than one initiators.
So basically you can't share roles across workflows, which is what I have been trying to do.
Is any of this documented some where?  Would have saved me several weeks worth of work.
