is anyone aware of a way to transfer layout (optimization) between documents?

in more detail: a large opera score, heavily optimized, each page differently

Now I noticed the layout of already finished earlier pages got somehow messed up (measure fit / system locks and horizontal note spacing is intact)

but the vertical space between the individual staffs is altered (mostly reduced...)

Now I need to copy the system optimization from the latest backup before this started BETWEEN DOCUMENTS.

With TGTools' great Staff Manager I can do exactly that- but not between documents :((

Is anyone aware of a way or a plugin that would allow this?

greetings, Dan
