Execute a Workflow upon the Rejection of the Request

Hi,


I am currently working on the approvals in vRA.  Through vRO, we create the entitlements and approval policies on the fly depending on who should be the approvers of the request.  This is all working fine so far, but I would like to know how we could setup a workflow to run if the request gets rejected by the approver.  The plan is to do a cleanup of the entitlements and the approval policies in this workflow in case the request gets rejected.  Is there a way to do this through vRO?


Thanks in advance!
