One thing to take into account is running "notmuch new" using
notmuch-command, and make that happen with one click in custom.

I just did this quickly to scratch my own itches, so to speak. My elisp
is not that great, so I really wouldn't mind if you wanted to continue
from here and make it your own. It'll be a while before I have the time
to (figure out how to) do this properly anyway. But up to you, really.

BR,
Jani.
