Is it possible to get notifications for containers with set version tags?

[OddMagnet]

Maybe I'm going at this the wrong way (probably), but here's what I want to accomplish:
I'm building a somewhat complex project with lots of containers and want to ensure there are no unexpected breaking changes.
For this reason I'm using set versions for my containers, e.g.

  watchtower: 
    container_name: watchtower
    image: containrrr/watchtower:${WATCHTOWER_VERSION}

However, I still want to be notified if there's a new version available.

Looking at the docker logs output for Watchtower, it is checking if there's a new version for the specified tag, which works well for tags like latest, but obviously not for "non-moving tags"

I do understand that docker doesn't pull new images automatically, even if my server restarts for some reason or I use the docker compose up -d command it should not pull a new image.

However, I'd still like to avoid removing the version tags if possible. Or am I being too irrational/paranoid here?
