Yes... Our group coordinator asked what table size we wanted. I asked for 10/2 and was told "sorry, can't do that". So we opted for the 8/4. You can even request which dining room you want. They tell you the dining room you get isn't always what you ask for, but we've been lucky I guess as we have always found our wishes granted. If you don't get the dining room you want you can find the Maiter D (he will be at a designated location when you get on the ship for table changes and such) and ask to change your table.
