Can I use the Mouse Wheel to do Player/Next-Frame and Player/Previous-Frame?

I would like my mouse scroll wheel up=previous-frame and wheel down=next-frame.
Can Shotcut do this or could it be an option on the roadmap?

Hover the mouse over the timecode spinner at the bottom of the player for that.

Thanks for the hover tip.
Can I make custom Next and Previous control settings in “Help, Actions and Shortcuts” so using the mouse wheel works no matter where my mouse pointer is?
I tried making a custom “Help, Actions and Shortcuts” setting that used the mouse but could not. I also tried manually entering the custom mapping into the ini file using “wheel”, “mousewheel”, and “scrollwheel” but no joy.
Could the mouse inputs be allowed in the custom mappings set in “Help, Actions and Shortcuts”?
