2021 New Captions background color on two lines

Off the bat I personaly wanted to say THANK YOU so much to all the hard work at  Adobe for updating this finally. Its AWESOME now!!!!

Only question concern I and my fellow colleagues have is will / can there be a way for 

two line subs like this one to have the background land exactly on the size of each line like the previous subs title sytem did? I think this is the standard way with two line subs are displayed so we really hope so.

So for example the background would be exactly behind "NARRATOR" and "with" on top line. Right now it is using the bottom line as a guide so you get all that extra background over the empty areas. Not ideal or pleasent looking.
