How to implement the function of using multiple items at a time?

It really depends on what you mean by that.
I'd rather not help with custom edits to avoid the headache, so good luck with that, man.

Seems I have found a solution to using multiple stat items at once. Find def pbBagUseItem, put these codes between the line of ret = false and screen.pbRefresh.

      max_at_once = ItemHandlers.triggerUseOnPokemonMaximum(item, pkmn)
      max_at_once = [max_at_once, $bag.quantity(item)].min
        if max_at_once > 1
          qty = pbChooseNumber(
            _INTL("How many {1} do you want to use?", GameData::Item.get(item).portion_name_plural), max_at_once
          )
        end

And add && qty > 0 after if pbCheckUseOnPokemon(item, pkmn, screen)
