Remapping greasepencil quick layer cycle

When the cursor is over the layers tab in the properties tab I can use up/down arrow to cycle through layers.

Is there a way to remap it so it’s available in the viewport / dope sheet?

This would be helpful because I use many layers and cycling helps me see what’s on each layer. (I’ve already suggeted a photshop style way to identify what’s on which layer in the official request place, but this is my best solution atm)
