Consider predefining your own configurations of healing items and potions. In the current situation, it is not possible to quickly select the item we need. While it is not noticeable during normal exploration, it is during the boss fight (Echo Knight). I would like to be able to put fire on the weapon during combat and then switch to the concentration regenerating vial. With such an aggressive boss, it is impossible to find the item I need at the moment.
I would like to be able to assign (under the lower cross) any number of elixirs that I will need. The same goes for healing items. I would like to be able to select what I want under the upper D-pads - instead of the entire inventory available from the menu.
Alternatively, leave it as it is and pressing the lower or upper cross would slow down the game time so that we can choose the appropriate item.
