Abilitiy to mix license types in a Trello Workspace?

[Saratech Marketing]

Does anyone know if Trello allows mixed licensing in a Workspace?

For example: 3 full-time team members buy annual licenses. During the summer, 1 or 2 interns would be added to the same workspace, but their licenses would be monthly and not annual since they will only be there for 3 months.

January - Buy 3 annual licenses

June - Buy 2 monthly licenses for a total of 5 licenses.

October - end the 2 monthly licenses and go back to the 3 annual licenses for the workspace.

Thanks in advanced.
