Library number on right top corner of a page

I have recopied just a single part into Dorico from and handwritten part. I have it all finished, which is only the second project I have done in Dorico 6 Pro, coming over from Finale. Please help me to place a boxed, "library number (48) onto the top right corner of my single page. I probably will need a step by step of how to make this happen on my new Dorico-created part.

Thank you so much for your time and suggestions.

I suggest you watch a Discover Dorico video about creating and modifying page templates (that’s a tool in the right panel of Engrave mode). Or try the webhelp (adding text frames in a page template).

Thanks so much Marc, I will give your suggestions a try.
