[Interest] table view click will "deselect others" when click pre-selected row?

[David M. Cotter]

is there any way to turn that OFF?

eg: if i have "row selection" turned on

and i have multiple rows selected
and i click in a row that is already selected...

i want it to NOT deselect other selected rows.  i want to intervene and do my own thing...

can i suppress the deselection thing on the mouse-down click?
