A way to re-order potions and traps on the D-pad

I finally found a way to set up the order of potions and traps. It's not elegant, but it worked.
First go to a merchant and sell all of your potions and traps. Warning you will not be able to buy these back. So it's best to do this after a battle before you re-equip or when your flush with shards and raw materials. I didn't bother getting rid of rocks, so my D-pad list was Mount Whistle, Lure Whistle, Rock. After you've sold everything, save your game, either quick or manual works.
Second step, Quit the game. I quit to the PS4 home so I don't know if this works by quitting to HZD's main menu.
Third, reload the game. You should now have an empty "tool belt" and an empty traps and potions inventory. Now you can either craft the items in the order you want them to appear, or buy new items from a vendor. Again buy them in the order you want them to show up. Don't use the "Buy Back" option.
To keep your list in your set order, don't quit the game with an empty "slot" on your list. Other wise the next time you load the game and craft or buy that item it will go to the end of your list.

A little history. In my first playthrough the full health potion got in a weird place far from the other health potions which was a mild inconvenience. In my new playthrough the health boost got placed next to the fire resist. Both are yellow, and in the middle of a battle this was big pain. Dropping items and then picking them up doesn't change the order. So from reading other reddit posts it seems that the order of these items is based on the order they are first acquired. After a lot of trial and error I've found that this is not exactly the case. Items appear on the "tool belt" in the same order that they're in your Inventory. The method described above "resets" your inventory.
Don't "Buy Back" your potions and traps, just let them go. For some reason this messes up the list. Bought back items go back to where they were and will even remove new items from the list. The new items will show up under Inventory but not on the D-pad. This even happened after saving - quitting - reloading, and after fast traveling far away and buying them back from a different vendor. And if you drop items, then save-quit-reload, those items will be gone. So selling them at least gets you some shards.

So Hey Guerrilla, It would be great to have a way to change the order of the items in the Traps & Potions Inventory. You wouldn't even need a new screen. Just a way to select an item, triangle or R2, then move it to where you want it, then deselect. Leaving the menu would save the new order. Just a thought, a suggestion, a request, a plea.
