Is there a mass PO delete option?

A bunch of PO's got converted in draft status. We need to reload them by fixing the errors. Is there a way to mass delete draft PO's?

Buyer Managed Transportation (BMT) was enabled and requested ship date wasn't populated. There is no way to mass update requested ship date on draft PO's and submit them, so we are looking at deleting the draft PO's and reload after disabling BMT.

Any inputs will be appreciated. Thank you!
