Nah, there are A1 roundels (yellow rimmed ) in the default game but they are repeated on the underside of the wings as well, and that's a problem. Actually for many RAF planes there should be a different roundel type for fuselage, upper side of wings and undersides of wings.

The best way to achieve this is to have the roundels directly on the skin for these planes (seldom used by other armies besides UK anyway...)
