How to list that I want to Buy a Map in bulk?

Selling Maps in Bulk is easy. But How do I list it the other way around?

With currency and stuff I usually fill a Tab with eg Chaos and list it that I want to Buy X-Vaal for Chaos. No issue.

If I try the same for Maps, it doesnt show up on trade.
Using the right wording and all.

Funny enough it looks like nobody has any listed Maps he wants to buy.

Im I just to stupid to check this or is this just not possible atm aka bugged?


Example:
Shouldnt this "~price 1/5 beach-map-tier-14" mean I want to buy t14 beaches for 5 chaos each when im listing this on a Chaos orb?

Case in point from today.
I noticed that I had not dropped Overgrown Ruin (T3) this entire league.
I looked the map up, saw 1 guy had 5 listings and whispered him to buy all 5.

When I got to his H/O, he indicated that he was getting spammed all the time for this one map, I pointed out that it had not dropped for me all league, AND I have played every day since March 13th as I was laid off from work that day.
He noted he had 8 so I bought them all.

TLDR: what I do is request to buy 2+ from a seller and usually get a good response as most sellers have more than 1 map of a certain type.
