MadVR - Save settings

Hi everyone!

I'm currently using SVP + MPC-HC + MadVR for HDR movies, and it works really well. But I have to tweak the black and white levels with MadVR every time I start a movie because I can't save the black and white levels. For example, with MPV player, you can save settings using a config file in AppData - something like this would be dope.

Does anyone know how to save MadVR settings?

Thanks
