Show component usage for dimensions & metrics

Description - We can now see where segments and calculated metrics are used.  Suggest we should be able to see the same for eVars, props, and metrics in AA/CJA.

Why is this feature important to you - At times some components may be obsolete or no longer used.  It would be nice to be able to see if & where these components are used.  When used, it'd make it easier to update with new versions of components as needed.

How would you like the feature to work - Similar to Used In column for Segments & Calculated Metrics search.  Clickable links for admins in setup screen, or perhaps data dictionary.

Current Behaviour - Without using complex API queries or 3rd party tools, there's no easy way to determine where components are used.
