Request fulfilled "Mark as Sold" Suggestion

When clicking the "Mark as Sold" button on a trade. The following page has a field to input the persons name the trade was completed with.

Would it be possible to have this field auto-populate with names of users that have replied to that trade? That way instead of having to copy/paste or manually type the username, you could just select it from the list of users from that trade thread.

Cool idea, down for that.

Cheers, sorry to add to your likely ever growing to-do list though.
