I need this feature as well. Many customers that are using it for remote access. Been experimenting creating other solutions, but I am no Azure App or SAML auth expert.  Best solution I have so far is connect SAML to an tenant and add other users as guest user in that tenant. But I am unable to apply CW Control roles to the guest user. Works fine with non-guest users in the tenant. CW Control dev team should create and publish a Azure AD app at allows us MSPs to connect customer tenants to our CW Control instances. 

Just upgraded to 20.2.27450.7387 from 19.6.26378.7317 and still have same issue. I will contact support for assistance.
