Filter option for amount of trades of a single person for specific item

As it is right now, there is no good way to find out how many of a specific item is sold by a player in async trade. Whats there for sync trade in form of the bulk search is missing for async trade.
In first place, a filter option might be good, that enables searching for shops rather than specific items. E.g. a list of shops that sell at least 50 maps of type X.

For more comfort in selling, there should be an option to price a tab in async trade rather than each item individually. I can see why it is not there yet. Because it is handled by the tabs name and it would be able to be used as a scam. So the one-price-tabs have to be marked in a way that is unique and prohobited for other tabs. It must be a way, where a buyer can be safe, that there are no landmines in it and it is not "faked", liked named/coloured close to the unique way.

+1 on this.

Would also support implementing the capacity to set up bulk purchase packages (eg set a price on a full tab, and then just load stuff into it; loot delivered by remove only tab).

Until the game itself has built in architecture, of course, there remains TFT.

Edit: NGL, the more I think about that bulk tab idea, the more I want it as a feature. As a seller, I would absolutely love to have bulk sale tabs and just load stuff into them until somebody buys it.

Yeah would love to know how many maps,sanctum tomes,beasts etc. someone has in their tab before going to hideout. Would save hours of loading screens. And sometimes if its only a few items they get bought out by others with super-fast load times lmao
