Thanks @LostKobrakai. Looked into the 'Dynamic Roles' Its looks like an abandoned module from Ryan, but the up-to-date fork from @matjazp works. I saw your comment,
, and that's exactly the same problem I have with this module.
I would love to use this module as a base, or write a pull-request to have this functionality, but I am not skilled enough to do that.
The hook into 'PageFinder::getQuery' scares me to add the selector ```saas_id=user()->saas_id``` to my Saas module.
