Expenses AWE - two different routings

We are on 9.2 release 35

We want to allow Union Reimbursements in Travel Authorizations. We would like to have the workflow route differently for Union Reimbursement TAs from other TAs. Has anyone used two different workflows within the module?

For example, if employee belongs to union A the TA routes to approver B. If employee belongs to union B the TA routes to approver A and then approver B.

If the TA is non-union related, the TA routes to approver B (supervisor) then approver C.

Thank you in advance for any help.
