Please rollback the controller inventory multiselect to R2 trigger! As a player who has been playing this game for more than 150 hrs on PS5, here's my findings on the Patch #4 change:

1. It's much more time-consuming to use the current multiselect system. As a PS5 player, I have to long press Square button first, then press X button to actually multiselect, then perhaps another press of Square button for more operations. For the R2 trigger It's just R2 trigger itself to select. I can save at least 1-2 seconds on this. It will be accumulated into a massive amount of time later.

2. In the big camp chest if you multiselect the books, there will be Reading and Picking Up sharing the same X button. Not sure if that's a bug or something. And organising books in the big camp chest is a mess now.

3. This change makes the big camp chest organising a impossible job. Because now the X button is only for select after you long press the Square botton. Therefore, we can't transfer stuffs in R1 individual character's bag page to the big camp chest. If we press Square botton, there will only be a 'Move' option. But that's not for moving the things back to the big camp chest. So we have to manually transfer the things in our bag to the camp chest one by one.

I can see lots of people are hating the change and thinking it becomes hurdle for continuing play.
