It should be possible to change the columnnames in a table or matrix

When defining measures it's important to give them the best name to quickly identify there purpose. These names can sometimes be very long and not directly clear to an end user.

After dragging these columns to a table or matrix visual it should be possible to change the columnnames so they can be shorter and more clear for users.

For example below measures
Turnover
Turnover LY
Index Turnover - Turnover LY
Budget
Index Turnover - Budget

Should be in a table:
Turnover LY Index Budget Index
