Payment Request Approval Delegation

In PUM 33, some of the transactions are enabled for approval delegation in the Approval Delegation Framework.  The way the delivered functionality works is when an approver A delegates the approval of a transaction to another user B, and if approving the transaction requires B to have a certain role, the system will automatically assign the role to B until the End Date specified on the delegation request.

Suppose our organization uses MAC Request or KeyChain to have access approved to perform a certain function, will PeopleSoft still assign the role to the delegate successfully and will the delegate be able to approve the transaction without being approved in MAC or Key Chain? Is it possible to route the request to KeyChain when the delegate is being assigned the role temporarily?
