Our main enhancement for TDP 4.3 is on the Pivot Grid. One of the features is to export the data as a flat grid which is the main feature the user is asking for. Please ask the user to try the current Beta. I have attached screenshots on what we currently have.

What we do not have is an option to add to the Data Model. There is no API call for this so we can't-do this programmatically. Is the user just trying to hide the data tab? It that is the case we could see about adding that option. We are very near to RTM so not sure that would make it into this release.
Also, note that we have better export to Excel Pivots, as well as saving flat grids to local storage and publishing to TIC. Hope this help.
