I want to be able to just fund a bitcoin address given to me by the registrar, and the registrar withdraw payment as necessary when it is due for renewal. Is this possible anywhere?

All I've seen during my search require you to either manually go through a third party payment processor, or manually set up a renewal order so it can't be automated (without a credit card). A manual setup is fine, but I want to be able to let scripts handle it after that. Very frustrating.
