### Describe your issue:

…

I like to run two regular endstops on my dual Z drive axes IDEX printer.

I connected the endstops to the GPIO of the raspi.

The BLTouch is mounted to `[extruder]` (the left one, in difference to `[extruder1]` on the right side)

I like to use the BLTouch to create the bed mesh.

I there a way to say Klipper that the BLtouch is mounted to `[extruder]` as it was formerly done by `endstop_pin: probe:z_virtual_endstop` in the `[extruder]` section.

It appears that Klipper assumes the BLTouch to be mounted to `[extruder]`.

Everything works as expected.
