Trading from Premium Flask Tab is almost impossible due to unusable (x,y) flask indexing, need help!

I am not sure if i am writing this issue in right forum, but it is related to general help in PoE.

Issue: I set all flasks(500) in a premium stash tab on sale. Copied message is like

Hi, I would like to buy your Medic's Eternal Mana Flask of Movement listed for 10 chaos in Sentinel (stash tab "~b/o 10 chaos"; position: left 95, top 1)

the number 95 is totally useless in this tab, no way to count it


How to point out the correct flask if I have three flasks with identical prefixes and suffixes, but different rolls?

How can I report this kind of UX issue to GGG?
I can propose a UX solutions for this: to add visible enumeration in the premium stash to see (x,y) coordinates
Or add filter with x and y numbers to enter to locate the exact flask (i think the best solution).
Or add a short hash string to identify item in tab

I was totally unaware of this behaviour before buying four premium flask tabs

I will appreciate help on this issue

The REAL question is, what on earth are you doing buying four entire flask tabs?

If this ever happens to me I just give them the lowest rolled one and ask what the roll was if they complain.

All jokes aside, this is a niche but annoying issue, which also applies to the gem tab (but is less impactful as there are no divinable rolls on gems).

Or maybe trading all and ask which one? There are many cases with double rolls and there is no best or worst rolls
