Draw note length in Piano Roll

Could a small addition to the way notes are "drawn" into the piano roll be made to allow drawing the length instead of pasting either the last used length or a fixed set-before length?
Like holding shift and instead of moving the note around will it instead start where it was drawn and end where you let go of the mouse button?

I know that you can quickly copy a note's duration by clicking one, but I simply keep expecting to draw the length instead of pasting and then start moving a note when I draw them.

The issue identifies the piano roll's note-drawing interaction but names no files or tests. Start by locating that interaction and reviewing how Shift currently changes note movement; done means Shift-drag creates a note from press to release while preserving existing duration behavior.
