Setting Default Value based on Environment Test/Production

Summary:

Content (please ensure you mask any confidential information):

We have set a default value for Recruiter field in Create Requisition using AssignmentID actual value for a specific Recruiter. If we move this to Production then it wont work because this value does not exist on Production.

Is it possible to add a condition like:

If Env.Name = Test then set AssignmentID = X Else set AssignmentID = Y

or can we create a custom Profile Option and set the Default Value to the Profile Option value? How the syntax will look like?
