Roman Numerals with Figured Bass

I’m working on a publisher’s piano pedagogy book, and they are introducing figured bass. Following Walter Piston’s Harmony, they use Roman numeral chord symbols with figured bass intervals. How do I get that option to show in Dorico?

You use a font like MusAnalysis.
