Having COMPLETELY isolated members to follow the same course as the commmunity (being invisible to them)

I'm offering 2 COURSES OPTIONS right now:

• 1 for COMMUNITY members

• 1 for SOLO members

I'd like the "SOLO" members to follow the exact same course as the COMMUNITY but without being visible to anyone except admins (DM + Online members + anywhere else)

Currently doing it manually by creating tons of isolated groups cohorts for each "SOLO" members but it's not the best option as I have to update each cohort course individually…

I'd love to know if this could be made someday. Thanks!
