Automatic Permissions Mass update

Hi. 

Until recently we have been using M-files for a single small team and therefore had not applied any permissions. We are now rolling out to the wider business, and I setup a Named Access Control List which uses meta-data. I plan to use this via "Automatic Permissions" for documents per class. I've tested this on a single class and it all works exactly as I'd expect and I'd like to roll out, however it looks like I have to do this on each class... Is there a way of updating classes on mass for permissions?

Thanks
