Brush designer eraser mode toggle

[Boxy]

Hello Ragers
I'm loving the new options in AR6's custom brush including eraser mode which I already prefer to the main eraser. I'd love to assign a keyboard shortcut which toggles eraser mode on and off in Brush Designer, that way I would't have to stop the workflow to locate and click a button. So far I haven't found such a thing, is it possible? If not can we please please have the option? :D
Thanks

Plus one for this. This is preventing me from making use of the brush shaped eraser.

Plus one for this! It could save up to 5% of drawing time, i think).

I also need hotkey for smoothing option).

Anyone else having a hard time with pressure sensitivity using the eraser mode? I feel like it's hard to get an eraser to "erase" with low opacity...

Also hopin' on the eraser toggle key request!!

Just shooting this request back up to the top....
