Selection model

Is there a way to replace the selection model used by the grid and replace it with a custom selection model. I noticed that the built in selection model does not uniquely identify each selected row. For example I have seen a selection of "R1:R10, R2:R5, R4, R4, R6". In this case R6 is listed in 3 ranges. Is there sequence of calls that would normalize the selection list? In the example above, just R1:R10.

The is no specific functionality that does this. But the GridRangeInfo has helper methods that might help in this work. range.Contains range.Intersects / With range.UnionRange It would take a little coding.
