I have set the chart behavior to "Modify" but I want to turn off multi selection of tables by mouse.  User should be allowed to select only one table at a time.  Is there any way to turn off multi selection in "Modify" mode.  I know "DoNothing" does this and I could select items from the click evets, but I want the user to have the ability to move the tables around and that is not available in DoNothing mode.
