I just can't find any documentation on this.

How do I select multiple Tracks on a push 3 standalone with Ableton 12 installed?
I tried both- the public release and the beta release, but both seem to not have an option to select multiple Tracks on a push 3 standalone, and then manipulate their volume simultaneously, like it was always possible in the software and as far as I remember was possible on push3 standalone, with live 11 installed, by simply holding the select button and clicking on the tracks buttons you wanted to include in the selection- like you would expect.
Am I missing something?
It seems like there haven't been any complains about this online- at least I wasn't able to find that specific topic.
To my routine, this is crucial, so please let me know, if there is a solution.
Thanks in advance!
