How to change starting measure number

Helloo Musescorers!

I'm writting a document that is a jazz solo, only, lasting 16 measures.

The score itself is a separate pdf dodument and indcates that my solo starts on number want to add measure number 44... However, that document has the chord changes only from measure 44 onwards.

In a separate musescore document, I am writting my solo, and want to specify the starting measure number as measure 44... because my solo starts on measure 44 in the actual score.

How do I do that?

Thanks!
