Just to confirm my presentiment…
If I in Setup Mode in the right panel Add Full Score Layout I will get a score layout with all instruments ticked and all flows selected.
If I in the same panel Add Custom Score Layout I will get a score layout with no instruments ticked and no flows selected.
Basically it is just starting on two different ends of the same thing. I will in both cases have access to my (Score) Master Pages, also my individually prepared ones?
In contrary, if I Add Instrumental Part Layout I will only have access to my Part Master Pages.
Is this correct?
Can one Propagate a Master Page across from a Score Master Page to a Part Master Page?
I guess, there might be a reason why not?
Thank you for comments.
ps: I know I could figure this all out by try and error possibly
