This might be possible, but it’s a little tricky, and will depend on where your SummaryRow is located. If it’s in your FixedFooters then there is no way of doing this. However if it’s in your Footers then you could use a hidden column that has a flag that indicates which rows are to be included in the statistics, and you group by that hidden column.
Note that if you need to let your user have access to grouping functionalities this may get complicated. Also note that if the group by control is visible the user will be able to see that there is a grouping on the hidden column.
