Writing Dominant 6-65 move

Is there any smart way in Dorico to write following very common Hungarian harmony note above as lyrics or text? I’ve tried using MusAnalyisis as well, but couldn’t figure out how to achieve…

It should be something here, although i admit I haven’t done this in a while.

Thank you, Dan! I was studying these paragraphs of the tutorial but can’t figure out how exactly can I typea roman numeral (the grade) followed by an index number (6) and an next an other index mark: a line on the vertical height of 6 and right below number 5.
