Create common centralised rules/data elements shared across properties

I would like to be able to centrally manage a rule/data element and have the change automatically distributed across multiple properties.   We are managing several properties and have found that we have many common rules/data elements.  When we change how we want them to work we have to manually edit each individually or do a lot of copying between properties.

I would envisage a separate area to manage these common rules/data elements.   Within each property, there would be an option to add a centrally managed rule/data elements.  If a centrally managed data element was added to a property it would appear read only, apart from the ability to delete it.
