When clicking "Sell Yours", use the info and pictures I already added to the item in Collection.

I added 300+ games to my Collection, along with several hundred photos showing boxes, manuals, discs, etc. If I click a game in my Collection, then click Sell Yours, none of that info comes over, and I have to re-enter everything and search through tons of photos to find the right ones again. 

Maybe have a Sell This Item button in Collection that lets you quickly list an item without re-entering info and photos.
