extra_model_paths.yaml in WSL2 - how??

Hello, I wanted to give ComfyUI a try and do all of my ML work in WSL2 conda envs; getting the program itself set up and running was an absolute breeze but as I keep most of my models in my Automatic1111 area **_on my WSL2 filesystem_** I have tried multiple methods to properly input the location into extra_model_paths.yaml, but while I get no errors once I am in the UI I cannot select anything other than what is in the ComfyUI/models locations...

So far I've tried:
\\wsl.localhost\Ubuntu-20.04\home\myusername\ML\MC\sd-webui
\\wsl$\Ubuntu-20.04\home\myusername\ML\MC\sd-webui
\\wsl.localhost\Ubuntu-20.04\home\myusername\ML\MC\sd-webui\
\\wsl$\Ubuntu-20.04\home\myusername\ML\MC\sd-webui\

and with slashes facing the other direction - each one results in some variation of the expected terminal output:

To see the GUI go to: http:\\127.0.0.1:8188`

But in the UI itself no other models are available than what is in the ComfyUI model folder.
Please help me load my sd-webui checkpoints without having to move my folder outside of my WSL2 filesystem, because I just don't have enough room to do that and I have reasons for having them where they are.
