Can anybody help?
I don’t know if this possible, but you might like to try it.
Go into Engrave mode.
Click on the pedal line in the Coda - hopefully, some edit handles will appear.
Click on the edit handle underneath the left end of the line.
Either drag it to the left using the mouse or use opt/alt+left arrow to nudge it.
If you can’t select the edit handle (maybe because of things being very close together), in Properties adjust Pedal Lines > Start X offset.
