It would be great if Adobe Analytics allowed customers to identify variables in the Admin console as they wish instead of having to use "event1" or "event2"
If users could pick their own names, they could more easily make implementations align across multiple report suites instead of having to worry about pre-defined variable slots for events, eVars and sProps.
For example, if you defined internal searches as event.internalsearch, you could make that consistent in all implementations vs. having to make sure all report suites used the correct event number.
This would also make it easier to share objects across implementations.
