As of Hotfix #13, no. (or at least nothing was announced, and I can't be bothered booting the game up on PS5 to find out). I did submit another bug report about it a week or two ago, and got a response saying something to the effect of "we know it's an issue and we're working on it, but as of now we don't have an ETA on when it will be addressed". Which like... I guess it's good that they know it's a thing, but it'd be great if it was addressed in the near future so that we can go back to playing our games. I worry that with the release of the Xbox version that they won't bother rolling it back to how it worked in Patch 3, because the new players won't have experienced it, and might complain.

I do highly suggest besides posting here, that people join the larian discord and vote up the feedback posts about the multiselect issue/make feedback posts about it.
