We run a PPM system that uses SharePoint Online and Project Online - the system creates 6 permission groups for every project created - even test projects where a SharePoint site is associated with it. Now for us to clean up the groups - there appear to be only 2 options: remove them one by one (very tedious) or remove them using scripting (PowerShell?). I feel like there should be an easier way to view the list of groups and allow you to click-select multiple groups to delete them (or perform similar actions). This is how it works when you are deleting individuals from a group. You don't have to open each one then delete - I don't see why we cannot have the same ability for deleting groups.
