Assign existing teams to organisations

We are planning to migrate to Gitea - we are having more than 400 repos, about 100 organisations (groups/companies) and 3 relatively static teams of developers. We want to create 3 teams with assigned members and then assign these pre-configured teams to each organisation (group) accordingly (too much hassle to re-create teams per organisation). Unfortunately I don’t see this functionality available - teams cannot be shared between organisations. Please advise if it’s possible.

There is an issue for that but no PR to implement that currently.
