can PA please make "mass scrolls combining" 
when we click (+) we get a pop-up to tell us how many scrolls we want to get or even through processing!
instead of making them one by one and playing puzzles to arrange them
because when someone has +100 inventory  slot it's a pain

and here's my adventure making some scrolls X4 speed

make scrolls stack, remove the expiration.  Make it so that you have to have a multiple of 5 to summon a level, no longer putting in a completed scroll you just open the event with 5 more more.
