Hierarchical grid row expansion and row selection?

With a hierarchical grid and row selection. Can I preserve the row selection when expanding a hierarchical grid row?

Example:

There is a grid with five rows in it. One or more rows contain hierarchical grids present (rows 2 and 5). The user has selected rows one or more rows (1 and 3). If the user clicks the hierarchical grid row expansion icon of row 2 the selection of rows 1 and 3 are lost.

Is there a way to prevent this default behavior?
