Unreal Launcher suggestion

Would it be possible to add some option(s) to the unreal launcher to redirect where “My Content” is stored?

I would like to move it to a different drive simply to control drive space usage. I looked quickly through the registry to see if it was defined in a key like HKEY_Current User or Local_Machine.

I also thought I would use process monitor to find where it is set but didn’t find it.
