Enforce MFA for a Product, not for an organization

[Eicke Bücking]

Hi Guys, 

one question with regards to MFA enforcement: If I got the Atlassian Access documentation right, Access would enable me to enforce MFA for all user accounts related to my organization (matched via mail-domain, I assume). 

What I need: We are running a Confluence and a Jira instance in the cloud with users coming from different organizations, having different mail accounts. I want to enforce that access to these Products is only provided once authenticated using MFA.

Is this possible as well in any way?
