Change default behavior of "Update multiple tickets?"

When I click on “Update multiple tickets” the default is that all tickets are
checked. If I have 100 tickets in a queue and wish to update 12 of them, I have
to click 88 times to uncheck the rest (which makes the feature useless in such
cases). I scanned the manual, searched mailing-list archives and asked our
in-house RT expert but so far I have not found a way to change the default
behavior to have them start out unchecked. Does anyone know how to do this?

Give RT 3.5.6 a shot?
