If only it was that easy! I had already tried that but chaos ensued.
This is a multi page instrumental part where I am trying to coincide page turnovers with rests, and I am trying to get page 3 and part of page 4 onto a single page 3.
I have already merged page 1 and part of page 2 onto page 1, then then the rest of page 2 and part of page 3 onto page 2. so far so good. I am left with frame break labels at the begining of the new pages 1, 2 and 3.
If I then select the final bar line of page 2 and the bar line on page 4 as the begining and end points of the bars that I want as page three and do Make into Frame, I get page 1 in its original state and page 2, page 3 and the selected part of page 4 all together on page 2. I presume this is because the last bar line on page 2 is before the frame break label at the start olf page 3, but why this would affect page 1 I don’t know.
I think the solution might be to insert a dummy note at the begining of the multibar rest at the start of page 3, do the Make into Frame layout changes and then remove the dummy note. It does seem a little laborious compared with a rival.
