Default PATH settings of Documents

I am using PortableApps installed in a cloud (OneDrive), where my Documents also reside, but this is not the default Documents path of PortableApps. It would be nice to have the possibility to alter the default path settings in PortableApps for Documents, Music and so on, preferably by adding the correct path statements in PortableAppsMenu.ini. Is this possible, or could this be made possible?

Thanks!
