Ability to mix licenses

We mostly just use the "Unattended Access" features, and use provide remote worker access to a large number of people.  However, we occasionally do want to be able to conduct a Support session and use some of the features from the "All Inclusive" licenses.

I'd like to be able to pay to allow my technicians a couple of simultaneous support sessions, as an add-on to my otherwise "Unattended access" instance.
