Change chord symbol size in one part only

Is there a way to change the size of chord symbols for one part only? For example, if a piano part in a big band chart is mostly slashes, I can reduce the number of pages by making the rastral size smaller in layout options, but that also reduces the size of the chord symbols. Can I enlarge the chord symbols for that part only, leaving the default size where chord symbols occur in other parts?

You could scale them in the properties panel with set local properties to locally.

Other part:

I’d have to select them all to do that, wouldn’t I? Is there a way to easily select all chord symbols in the part? I know I could put the part in scroll view and select the first one and shift-select the last to get everything in between, but is there a more straightforward way to do this?

In the part do select all, then right-click>filter (select)>chord symbols

Or select the first chord symbol and press cmd+shift+A for select more a few times.
(ctrl+shift+A on Windows)

Oh right. I should have thought of the filter.

Thanks.
