Is there a feature in the app to make certain teams / users members of new organization projects by default? Currently when a new project is created, someone needs to log onto the app to add the internal-pulumi-admin team each time.

we don't have that feature currently. would you mind opening up an issue? https://github.com/pulumi/service-requests/issues/new?assignees=&labels=kind%2Fenhancement&template=1-feature-request.md
