An option to clean the slate?

I'm curious as to weather or not you could add an option to eliminate votes off a pre-existing shirt to give it a fresh start once it's re-workshopped.

I have shirts in my workshop right now I'd like to re-do, and re-sift, but the score from the originals are so low it would be somewhat difficult to get a decent score now, because if people who voted before are no longer here voted 50% or below, it's a permanent blemish on the shirt.

So, what about an option of wiping all votes off the shirt upon a workshop re-submission?
