Currently if you need to revert a lot of Projects to the Global Default, you have to do it one at a time. This can be extremely painstaking and time-consuming if you have more than a few Projects to revert.
Could really use a way to do this en masse, either via some mechanism in the UI, or by enabling an API function to revert to the Global Default layouts.
