Approval Configuration (reviewers)

Has anyone added a reviewer in the Approval steps for Vouchers that would get notified after final approval if the voucher Amount was > a certain amount? It appears that indication of a reviewer occurs at the Configure transactions page to add an additional participant for the event "On Final Approval". But not sure how to qualify that the reviewer should only be notified with Voucher > a certain amount.

@Julianne Hope -Are you using the AWE workflow or is this an earlier workflow process? Along with that, what version of PS and PT are you on?

e.g. AWE --> eProcurement > Administer Procurement > Maintain Workflow > Approval Process Setup

@Julianne Hope Hi Juliann,
We have a Reviewer User List added to a step, but don't currently have a Reviewer On Final Approval.
Have you tried adding a new Step to the Path so you can define the amount criteria you want and then only select a Reviewer User List?
I tried this in our non-PROD environment. I did not have a chance to test any transactions, but it did allow me to save the approval process definition with only a Reviewer User List on that step.
