Provide Bulk Column Configuration

The current method for adding columns and changing their Data Content type (value, average, min, max, etc) is clunky and time consuming.  You can only change (or add) one column at a time, and you have to wait for the data view to refresh after each change. Ideally, I would like to have the ability to switch from the default UI (Column headers with real data) to a configuration UI that has a more tabular configuraiton layout or a layout similar to AF.  I want to be able to select multiple data items and change them all to be "Average" instead of "Value".  I want to be able to rename one column and then quickly move on and rename another without having to wait for any sort of delay or processing.  Ideally, I'd like to be able to export the configuration to JSON or csv, edit it, and then import it as well. This would greatly speed up the views that I publish that require average values for all of the tag data
