How could I make a master page be available to other documents?

So, I created a master page which I titled “Hymnal” in a different document. I would like to make that master page available to every document in Dorico that I own. How do I accomplish that?

Short answer: you cannot (yet)
I would love to be proved wrong on this one!
For the time being, what you CAN do is setup your document with all the settings you need, leave it empty and use it to start any new project (save as…) or import flows from past frojects in it.
Hope it helps!

You can also ask Daniel at Steinberg if he is willing to do this for you.
