Add option in Admin Center to stop autogenerating a new site every time a O365 group is created via Teams or Planner.
When a user creates a new Plan in Planner or a new Teams Group it automatically generates a SharePoint site for that new group. This results in numerous random site names in a variety of formats. We are doing reviews with users to show them how to append the Plans to an existing group and how to create Channels within a group in Teams (to avoid a Site being generated) unfortunately the defaults on both are to create a new group and there is no option in the Admin center to change that or block the option.
There is a way to block users from creating groups with PowerShell but it would be be helpful if we had an option in the Admin center to block that option forcing them to attach it to an existing group, block it from individuals with certain permission levels or something we can use in Power Automate to trigger an approval process when they do attempt to create a new group.
