Should the creator of a payment request be able to cancel it on its own?

[CrsiX]

Currently, a creator of a payment request might stop ("cancel") it using the /pay stop command. Is it a good idea to add the feature that the payment gets cancelled automatically in case the creator disapproves himself?

Note that the creator of the request might not have the right to vote on payment requests because of not being an internal user, for example. This request would add yet another hole in the standard handling.
