It would be great to create like a MASTER Property (like a library) where rules and extensions can be committed to other properties. So the Properties can easily inherit the rules and extensions from the MASTER. If a new property is created you can then link it to the master and it gets all the data-elements, rules and and and.
Would be extremely helpful, otherwise we have to create each Pageload rule again and again. I know it is possible to copy rules from property to property but an automatically inherit would be so valuable.
