Internal req for PCard purposes

We are in the process of using PCard for some of the purchases made by departments. Our purchasing office wants to have an internal approval similar to requisition approval hierarchy for those purchases but do not want Purchase orders created for them.

Is it possible to create an internal requisition of any kind that goes for approval based on the current hierarchy and gets closed ? This is just for tracking purposes and do not want to go to buyer queue or the vendor/bank.
