C13 Mixer side slider to be added to the Midi remote

Ive always found it very tedious and real pain in the arrrrrrrrse to find either a blank space in the mixer channel strip /insert areas and use the mouse wheel to scroll up and down the selected slots .
Can we have an up/down command for the Lego remote app .

Yes i know about the side slider but you still have to hoover the mouse over which still is a pain and workflow killer
