Clarity on the "Selling" part of the listed sales

When you create a listing to sell a specific item, it seems like currently you can either put nothing, which will default to "open to offers" or add 1+ items you want to trade your item for. Currently, if you put multiple items in, the current system will put a "+" in between each item - which implies that you would want multiple items as payment for the item you are selling (e.g. for my Binky Kick, I want a Purity + a Rook). I was making listings just assuming people would understand that all the items I listed would be valid trades for the item I was selling but I don't think that is universally interpreted as such. Could we have a way to list if we want multiple specific items as payment (like the current system with "+" between each item, but also a way to list that you are open to payment with different distinct items (for my Binky Kick, I would take either a Purity or a Rook as "payment") , rather than just an open-ended "open to offers"? The ideal would be to perhaps separate stacked sections in which you could list what would be acceptable payment.

So for my totem, I would take:

Purity + Rook

OR

Totem X + Totem Y + Totem Z

OR

5 million Whisprig

Sorry that was long-winded, but hopefully made sense. Feel free to @ me for further clarity. Thanks Cam :)
