No, i guess this is a right that is reserved for the staff and not for us "normal" users.
I made the experience that only 2-3 of 30~ of my trade threads get pulled again to page one because people didnt see that i already sold my items.
If lets say Person A offers 30fg on my items and i accept that offer, i just qoute him and say "pmed", or i write nothing and after i trade i qoute him and say "thanks for trade". (Of course without double posting)
Usually then noone bump my topics anymore
I dont see the urge because a few people dont read correct to add that option. Just let the thread die after your last post mentioning that the item is sold.
