Repeated triplets simplified

Hi there, how can I recreate this repeated triplets in a simplified form?

Simple: Write another 16th-note triplet, fill it with a dotted eighth, and add the 1 stroke to it. Select it (including the 3!), press R to make more, and repitch them as needed.

To add the slash, select the dotted eighth, type Shift-R for the repeats popover and enter 1 (or /). Or you can set the slash using the right panel (the “first ending” icon).

Caveat: This only plays back 2 regular 16ths. There is a workaround if you need correct playback.

Perfect!
Thanks.
