Is it possible to modify Rhythm Slashes?

I have some bars where I would like to indicate rhythm slashes of: quarter, triplet, quarter, triplet. Is it possible to modify the rhythm slashes? All I can get it to show is four slashes. I’ve tried selecting slashes and pressing “;” to implement the triplet ratios but nothing happens.

Instead of using a slash region, go to note input and use Alt-Shift-V to create a new slash voice. You can then input whatever rhythms you want, just as you would input normal notes.

You can also break a slash region at any point, and move the end points if you want to insert a bar of a specific rhythm in the middle of a long slash region.

Brilliant, thanks!
