Copy/pasting notes from old to new bars

PLease create a way to write a short series of notes and copy/paste it into rest of the measure of the song you’re working on, instead of having to create each beat individually. Have you ever had to build a 16th-note tamborine part for 8 measures? It’s a pain. Why not be able to write 1 bar of 16th notes, copy it, and paste it into subsequent bars?

Highlight the notes, ⌘+C to copy, then click at the point in the measure you want to past them and ⌘+V
Also, if you write 1 bar of 16th notes and click “Double Beat” you can quickly built out a section from a base set of notes (it duplicates the notes as it doubles the length)
Hold ⌘ as you increase the bar count and it duplicates the last bar notes as it increases
Hold ⇧+⌘ while you increase the bar count and it duplicates the first bar as it increases
