OnRowSelect clears previous selection

Is there a way to preserve previously selected rows during onRowSelect event? I tried to call SelectRowById on OnRowSelect to preserve the previously selected rows, but it doesn’t retain the old rows. This OnRowSelect event seems to clear the previous selections. I tried to get the rows that were checked using getCheckedRows and manually check them again after my new row is selected, this also doesn’t seem to work.

Thanks!

Unfortunately this is not available to save the history of selected rows.
