Tie to Previous Note Command

Hello!

The "toggle tie to next note" command adds a tie from the current note to the next one using the comma keyboard shortcut. It would be great if there was the reverse: "toggle tie to previous note" as well. My current workaround is to press the arrow key to go back to the previous note and then press the comma key. However, it would be more efficient if this could be done in a single keystroke.

Thanks!
