Need Quick Help: How to customize datagrid selection to only certain cells in AS3?

Hi,

I want to select multiple cells. I see datagrid.selectedIndices[1,2,3] selects a number of rows. But is there a way to select multiple cells (not necessarily complete row/columns)? something like select cell [0,1] to cell[1,2] would select four cells??

Any pointers to help resolve this query would help.
