How to Setup Multiple Cloudflare Access Portals with a single Account?

My enterprise account has multiple domains added to Cloudflare. There is a requirement to create multiple Cloudflare Access portals where a user will login via Azure AD and depending on his Azure group membership he will be presented with the corresponding portal page.

From what I can see, Cloudflare Access only supports a SINGLE portal for the entire domains in a single account. Please advise if there is a workaround so we can create multiple portals. Thanks
