Changing Clickbank Affiliate ID in the middle of a Subscription?

I just realized the affiliate commisions from my PPC Bully 2.0 subscription are NOT coming to me. I rememeber when I signed up with a blank ID. Back then (November?) I didn’t have a Clickbank account and it hadn’t dawned on me I could be my own affiliate and get a discount. Damn. I’m going to have to “rectify” this.

I wonder… Is there any way to change the affiliate associated with a subscription without canceling and signing up again? Should I give Clickbank a ring?
