(Layout questions) Diferent staff spacing for different systems
I am trying MuseScore, specially regarding layout, and I have a question. I created an orquestral score from MuseScore's default templates. The first system started in page 2. After I changed the bottom margin of the page from 20mm to 10mm the first system went to page 1. But, because staves have the same distance between them, the whole system on page 2 was higher than page 1 (because there is no title on page 2, of course). Now I want the second system, on page 2, and subsequent ones to fit more evenly in the page. To do that I would put more space between staves, making the last staff of page 2 be at same level as last staff on page 1. But, if I do that in Style -> General -> Page, it changes the distance in the whole score, and the first system goes back to page 2. So, I wonder if there is a way to set the Staff Distance for the whole score and then reduce staff distance only in the first system (or in a specific system in the middle of the score).
I am attaching the file I would like to change and a PDF of what I want.
I hope someone could help me with this question.
