I prefer to write and display Csus7 for a C-F-G-Bb chord, but Dorico seems to want me to enter C7sus.
For starters, I’m unable to “teach” Dorico my preferred chord spelling in the Project Default Appearances. I’m not sure what I’m doing wrong, as I’ve done this successfully with other chords in the past.
But the preferred method would be to add this as an option in the Chord Symbols menu - the ability to place the sus before the 7. I know chord symbol formats are notoriously varied things, but I believe this is a reasonably common way to display this chord. It’s how I’ve always done it, and it’s how I’ve often seen it displayed elsewhere.
