Buying & Selling Full SETS pathofexile.com/trade

Bug report - 541 297 731 Dont know if its needed.
To the issue
It's been a while and its already frustrating.
Please fix the option that allows us to search for whole sets in the in bulk trading.
Currently we are unable to search for a whole set and what i mean by this is
Atziri Set, uber atziri set, Shaper Set, Elder set etc. all of those we are unable to search for and i believe that this is a known issue that happened when the change that made the separate fragments to be abled to be stacked was applied some time ago.
So please fix the search so we can buy and sell full sets instead of their parts.
