Hi! I've implemented a rough draft of what this could look like in #3534 but I think some discussion on the correct API for this would be prudent! Please let me know if something like that would fit your use-case.

@joshmeek thoughts?

This will take additional work to add to all of the notifications and update documentation, this would be a good issue for someone from the community!

@madkinsz I'm guessing we would want the template to be "templatable" so I think something similar to what we do for task targets would be a nice implementation. Task targets can take in templatable strings like "{task_name}-{today}" but for the notifications we would run with a slightly different set amount of templatable variables. Looks like tracked_obj, backend_info and state are the reserved values that are available to the notifier at runtime. The notifier also has context available so we could use variables from there.

Hi all, there are some comments in the relevant PoC PR and this is ready for anyone in the community to work on.

Hey @madkinsz, that looks already like a great framework in which to bring this functionality to live indeed!

Unfortunately, I am still pretty busy at the moment, but if nobody else looks into this, I might be able to finish it in ~10 days :)
