Configure Integrations for Groups

I have projects grouped together logically by team; to that end - I would like to allow the configuration of integrations (JIRA, Slack, etc.) for all the projects under that group to be setup at the group level, but I can’t seem to find a way to do this. If nothing else, an API that would allow me to configure each project individually would at least allow me to configure all of them the same way at once.

I am on version, not the self-hosted version

Any ideas?
