If you mean electrically controlled, the answer is maybe. The problem with most hydraulic/electric controls is that they cannot be feathered. In other words it is either on or off, as is the flow to the cylinder. This not very conducive to smooth operation. There are some systems out there which allow proportional flow with electric controls, not particularly designed with loaders in mind and not particularly designed with economy in mind either. That is why most loader mfg's use cables to remotely control valves.
If you mean a hydraulic joystick valve, there are several available. but you will have hoses very near your body, which may or may not be very comfortable.
