Allow user preference for saving settings

I'd like a setting to allow Tabular Editor 3 settings to be stored in a user selectable folder. I want my settings (Preferences.json, MacroActions.json, etc.) stored in a OneDrive location so they are both backed up and can be easily sync'd between multiple PCs. Or a cloud account to store these settings where logging in retrieves them, but I suspect a local folder sync'd via OneDrive would be easier.
