It is partially possible.
You can set autoShots to 8 or 15 or some other high number, and set your tuAuto to some appreciably high value (probably 50 or higher). This will make all auto shots fire that many shots.
(OXCE+ only)
You can then set sprayWaypoints to 2 or 3 (or more) in order to be able to fire the auto shot across a set of waypoints.
The end result is that you mostly achieve the shot functionality albeit it's called auto shot rather than burst fire or full auto. The only things you can't do are two kinds of auto shots on the same weapon, and spending energy to fire. (as far as I know, anyway)
