Hi (and welcome 
),
There’s a few preferences you can tweak at Preferences: Notifications – Django (you need to be logged int), but as far as I know there’s no option to subscript to a specific component.
That seems like it would be a useful addition though, would you mind creating a feature request issue at Issues · django/code.djangoproject.com · GitHub?
I’ve done a quick search and haven’t found any plugins that would offer it, but we might be able to develop our own.
