Monitoring Mode to continuously update depots

[MeFisto94]

So, apologizes in advance if my question/terminology feels off, but I essentially want to ask if there's a mod (or auxilliary software) to keep monitoring an app_id and continuously download new releases, preferrably in dedicated folders, so one can keep track of releases and still have them, even if they'd get yanked/inaccessible after some time and also to maybe have automated data processing and notifications
