Yeah, this feature has been requested many times in the past. It's a
tough nut to crack though, which is why it doesn't exist today. I had a
patch partially working that did it, but there were a number of areas in
the code I couldn't figure out how to change, and after spending much
more time than I should have, I abandoned it.
I have learned a few more things since then, and maybe if I attempted it
now, I could make it work. But I have no plans to work on that at
present.
It is not impossible, just pretty difficult.
