DTM - improve Data Element management

[#1]

In genearl, it would be really super great if Adobe made improvements to DTM as far as global configurations/tools/data elements/rules that can be globally applied/managed across all DTM properties.  This idea is about Data Element management in particular.

It is really hard to maintain a lot of Data Elements across multiple DTM properties, making sure they are sync'd / updated.  It is a very painful manual process

Please add option to overwrite existing Data Elements when copying to other DTM properties.  

Or better yet, please create a global data element interface that will cause them to appear in all DTM properties (or all specified properties) and updating them will update to all (specified) DTM properties. 

Also, please add a section to the data element's config screen to show where all it is currently referenced.
