Like others here I also made this account for the same reason, loss of the R2 trigger for multi select really hampers inventory slew tion and management across a bunch of gameplay features that a rather crucial to the game, such as accessing the camp Chester and moving items around and between containers.
The R2 worked perfectly, whereas the constant pause to hold square and then select with X is much less fluid, breaks immersion as I want my looting to be fast so I can get back into the game, and it also provides greater room for error where instead of moving gear I end up equipping it because I've pressed X again instead of moving onto the next item to select with it.
Please bring the R2 multi select feature back
