Hi! Forgive me if this has been covered elsewhere (I could have missed it when I looked) -- but is there (or can there be if not) a way to cancel a send "ticket" after you've created it?

I'm finding cool profiles that I want to send to, then when I click through to get their info, I'm discovering they're people I've sent to before, through previous versions of the site. Having not gotten any kind of response from them, I don't exactly feel great sending to them again....but now I have this open send created for them. I don't like having these open commitments, but I also don't want to waste resources/time or bother anyone.
