Add Select All / Deselect All options for Groups Event Configuration > Restrict to all Event Types

Most of our Groups are allowed to use almost all of our Event Types. So when indicating "Restrict Creating to these Event Types", it would be helpful to be able to click a 'Select All' option and then uncheck the ones they are not allowed to use. I suppose a 'Deselect All' option might be helpful for other institutions if they only allow each group to use a few Event Types. Thank you!
