Please add the option for aggregates to be calculated dynamically by the datasource without requiring the grid to carry out a full refresh.

The current workaround from forums is:
save: function (e) {
  // Refresh aggregates when editing
  e.model.one("change", function () {
    gridDataSource.fetch();
  });
},
but as this triggers a refresh of the databound grid, it's current focussed cell is lost.

Example methodology for expected behaviour of solution:
1) A Config Flag on a datasource to recalculate aggregates when a value has been changed (only valid when aggregates are calculated locally) - this stops from requiring the save event.
2) Add support to the grid so that if the aggregates are updated then the grid will only refresh the footer rather than the whole grid. Alternatively the grid could always keep the currently focussed cell between refreshes (assuming the row has not changed, track by model's id field?)
