I have experienced that “Propagate Properties” does not propagate the custom scale of Segno mark.
“Segno” mark of Dorico is relatively small. Thus it is not easy to find it on scores.
I increased the size using the “custom scale” in “Custom” tab in the Properties panel, then tried to synchronise using “Propagate Properties”. However, it does not work.
Is there then a way to enlarge this symbol generally?
I changed the size of “Repeat Endings Font” of “Font Styles” in “Engrave mode”, but it does not change the size of “Segno”.
So that there’s a text searchable answer: it’s Engraving Options > Repeat Markers > Design. There are two settings for Scale Factors. I find 150% works well.
Engraving Options should be project-wide, so no need to Propagate.
