Row Totals(Grand Totals and also Sub totals) on top of Dataview

Row totals if we can get on top of dataview would have been great. With Summer release I see that there is a feature, which allows the user to see grand totals on top of the dataview, but the sub totals still remains at the bottom. Its an ask from a few customers I have been working with to get the sub totals at the top, it helps them avoid scrolling and checking the sub totals.
