WA when appling service bulletins it would be nice to expand the window

The window for the vehicle list is not able to be enlarged. When maximizing the window, it does not allow a larger number of vehicles in the display. When selecting a large number of vehicles from the list, it would be nice to not have to scroll through so many different sections of the display.
