Externel MCU pin polarity

General Discussion
1

Hello,

I am making a printer head PCB with RP2040 MCU and TMC2130 driver. The problem is that I am getting error when try to invert the driver cs pin polarity.
My topic is related to this one: Syntax error on Multi MCU pin with reverse polarity (!) · Issue #161 · Klipper3d/klipper · GitHub

So when I try
cs_pin: !head0:gpio18
I am getting
Unknown pin chip name ‘!head0’

I can not find the right way to do that in the documentation.
Can anyone help?

Thanks in advance!
