Hey Bob, I hope you’re doing well!
The three solutions are all compromises (I am grateful to Michael for taking the time to help!!)
1/ you can have different fonts and sizes in one Rich text box, so if you can make that work, do… it didn’t for me
2/ you can use two layers, one with text and the other with text and background (in premiere you’d still have to have two layers, one for text one for bg)
3/ use fusion to create whatever text you like!
that’s pretty much it. in case you want it, rh mouse click to download from my site at https://videoblurb.com/mp/title4mark.drp
