Equal instruments numbering

Say I have a score with four trumpets, three horns; alto, tenor and bass trombones, euphonium and two tubas.

Following the manuscript score I am engraving, I want the trumpets to be named trombe – that is; tromba I, tromba II, tromba III and tromba IV.

The closest I get is “Tromba I 1”, “Tromba II 2” etc. – the Roman numerals I want, followed by the equivalent Arabic numerals, which of course is a great assistance from Dorico in ordinary cases.

So: is there a way to exchange the Arabic numerals with Roman numerals in the score?

Not yet, Runter, but we will add this as soon as we can.
