Permanently changing Rehearsal Letters to Numbers in a Flow

I would like to use Rehearsal numbers instead of letters throughout the flow. I did change the “Type” and “Index” for the second movement to 6 since this instrument doesn’t play in the 1st movement. However, every time I add another Rehearsal Mark using the “shift+A” popover. What am I missing that will make this change permanent? When I change the “Type” the sequence remains intact. I would like to just use the “Shift+A” popover and have the next number in the sequence appear without having to change the letter to numbers every time.

Thanks,

Alan

Welcome to the forum.
Engraving Options > Rehearsal Marks > Sequence Type. You may need to undo the changes you’ve made to individual rehearsal marks.

Thank you. Didn’t dig that deeply. Awesome.

One good place to start: https://www.dropbox.com/s/rhq2udlfq985m7b/A%20Beginner's%20Guide%20to%20Dorico.pdf?dl=0

Also the Dorico YouTube channel. And the online manual is very thorough (through 2.2).
