Knife Tool: making switches persistent?

Almost every time I use the Knife Tool, I want to “Cut Through”, but every time I invoke it I have to reset that switch.

Is there a way to make the CUT THROUGH persist between invocations?

Blender 2.93.5 has two knife tool shortcuts by default:

K - occlude geometry yes, only selected off
SHIFT K - occlude geometry no, only selected yes

If SHIFT K is too far or you just want to cut through being on by default disable occlude geometry in keymap preferences:

Excellent news! That seems perfect.
