Thanks for the interest but it is unfortunately more complicated than what is proposed here. There is still a (long) open PR to implement what you are after that has a lot of feedback filed already. If you are interested in seeing this through, I would suggest pinging there to see if you can take it over and then addressing the outstanding comments
