Bar numbers for alternative endings

[Romanos]

This is not currently possible natively. This was just being discussed yesterday:

Bar Numbers and Repeat Endings

Hey there! A common convention regarding Bar Numbers and Repeat Endings is taking the Repeat Ending boxes (1.2. etc.) and treating them as a single measure (the same bar number). Currently, Dorico assigns consecutive Bar Numbers to Repeat Ending measures, and this behavior can be changed by adding a Bar Number Change easily, but it would be great if there was an option to not count Bar Numbers in Repeat Endings. I attach an example of a Henle Edition that shows this kind of numbering. Thanks! …

It is possible, of course, using shift-x text, matched to your bar number font. It’s just a little manual work.
