Do you mean a diagonal across the tops of the ceiling rafters?
Yes - diagonal bracing on the tops of the bottom boards in the trusses.

You may want to add the ceiling Eddie was talking about after you see what all ends up living in the open truss space. Or maybe birdlime is a favorite encounter for birders. You are building heavy enough to hold it up no problem, IMHO.
