This would be a huge re-work, and would consume a ton of dev time to build the new interfaces, and re-work how the storage is managed/handled for an update that wouldn't benefit players too much, and isn't even available to UIM on OSRS. This would definitely need to be polled so that players can vote whether they would want all that dev time focused on a change like this.
I hope there can be time made for this, because this is almost needed, but it is how OSRS handles it. Adding items to poh, and not allowing to take out, until set is complete. i support this 100%. my goal is too complete poh treasure room on uim and its VERY VERY VERY TEDIOUS, i could even lend a hand on pointing out the items that are currently bugged inside the chests/not added etc.
Current zulrah stash/inventory due to having 0 combat and wanting to complete alot of "outfit sets" but... it requires FULL to stash, so its okay.. if i hit over 2/3 items i'll hold, if not i drop.. then as soon as i drop, i usually get the item. black T and bronze G could be completed even.
