Please integrate the option to shift + rev or other combination to access hotcues 5-8. Something similar to the x1mk2.
If you can live without the SHIFT+HC = delete hotcue, you can set SHIFT+HC to access 5-8. Go to the X1MK3 control panel to select the 1-2 and 3-4 controls for the SHIFT layer.
I'm a big fan of shift+ hotcue for delete. Not so much for accessing 5-8.
