5D4, any way to quickly toggle between manually set and auto ISO?

[Kit Lens Jockey]

Like the topic says... Is there any setting or any button I can push or set up on the 5D4 in manual shooting mode to quickly toggle between a certain manually set ISO, and auto ISO? Sometimes I'm shooting in an environment where there is generally a good ISO that I have set, but something will suddenly change, lighting wise, and it would be nice to just hit a button and toggle to auto ISO, then hit it again and return to the ISO I was just at. It's a little slow and cumbersome to scroll all the way through the ISO scale to get to auto ISO in this circumstance, then scroll all the way back to get to the ISO I was at before.

Thanks.

Register/recall shooting function? it's in the customizing camera section of the manual, around pg 500

Set it up in M with your desired fixed iso, go to "Custom Shooting Mode" in the yellow menus and "register" in C1. Then change to auto iso and register in C2. Check "autoupdate" so it registers any change in the manually set iso.

I actually meant the custom shooting function you can pull up with a button (* or AF ON), since op wanted a button quickly rather than flipping the mode dial. You can set a custom ISO, SS, aperture etc to recall with a button press
