Different page sizes across different layouts

[Danix78]

Excellent @alin89c !
Some time ago, I too had forwarded some requests, including this one:

request for score

hi, required for score, if possible, in a future version, have: customizable page size for each layout: layout 1 A4, layout 2 A3; add / remove staves / tracks; move the order of the staves, eg. before/after. Thank you

I hope they listen to us.
