How to organize an Organization when you can't become an "organization"

Hello! I’m part one micro-division of Columbia University and I’m trying to figure out how to organize my team well in Asana. We can’t utilize the “team” option because a different micro-division of Columbia University already has created an organization based on the handle “@columbia.edu”. Does anyone have an idea of how we can organize projects by team without having the ability to use teams? I’m thinking potentially using different workspaces for each team but then not sure about the collaboration across workspaces… Please help! TIA.
