Even though the Pocket Pistol/Baby Dragoon has a loading lever, it is so short as to be pretty hard to use. You should be able to remove a properly fitted wedge with your fingers, you have to tune it so it can. This, however should be done only after a bit of shooting to break it in and seat the parts.
I can disassemble the 1860 Army I have an R&D drop-in cylinder installed in with my fingers to load/unload the cylinder. The only difficulty you might encounter lacking a olading lever is removing the barrel if the arbor is too tight. That must be checked for burrs etc. The wedge should go in until the hook of the spring just reaches the frame slot on the right side.
I would get a loading stand from Dick Dastardly or similar off the gun device to load on, or make up a lever and plunger similar to the one used for the Paterson Colt, that, with the barrel removed, uses the wedge slot as a fulcrum to seat the ball. If you really want simple, you could make a ram of brass or aluminum with a concave ball fitting end that you can use with a mallet to seat balls, and perhaps if it's long enough you can do it without disassembling the gun.
I use a loading stand (Dick's previous model) to load multiple cylinders for the cap & ball guns when I shoot a match, and have enough cylinders to shoot at least 4 stages before I have to reload a cylinder.
