i did find this thread Replace audio file in pool - #9 by dragon17 where i think the same thing is discussed.
apart from someone trying to argue that we do not need this functionality (although every other daw has it implemented), there’s also some possible helpful advice here (holding shift+ctrl while importing on top of the old version).
but this is only if the old version is still in the arrangement. i’m talking about when it’s deleted from the arrangement (for that time being), which happens quite a lot when you’re importing stems for mastering or collaborate or use different daws simultaneously.
for one thing it’s a hassle to remember which files are overwritten and no longer used and delete them from the pool manually before importing an update.
i mean, why can’t importing an audio file just be showing… the actual audio file? anyone can show me what i’m missing here? : )
