How to dynamically populate Change Management role?

Hi -

I have set up our Change Management roles to prevent the Change Requester from having edit permissions on the Close stage, and I created a new role called "Change Closer" to fulfill the role solely of closing changes.  The idea is that this person must be different from the Change Requester.  However, I cannot seem to dynamically populate it when the Change ticket is submitted.  Ideally, I'd like to open the form and based on whichever user is in the Change Requester field, choose one of their peers as the Change Closer role.  This could possibly be done by the Group field as that would be a listing of their peers (themselves included, however).

Unfortunately, on Field & Form rules there is no visible field on the Execute Script screen that could be used to accomplish this.  About all I seem to be able to do is make "Change Closer" a required field / role on ticket submission and rely on the Change Requester to put someone in their manually that is *not* themselves.  I'm not sure this will pass our audit requirements.  Any ideas?
