You bet this is possible.
Personally I like to siphon the beer out into another container to mix in priming sugars there so I can at least be consistent when I screw it up
. If bottling directly from "primary" or "secondary", your disadvantage will be that you'll need to pay close attention to where the upstream end of your racking device is sitting. Too low and you'll pick up trub/sediment. Too high and you might lose suction. All this time the other hand (or person) is handling the task of putting the bottling wand into each bottle and avoiding overflows.
I have bottled alone a few times, and so far the process has involved broken bottles each time. This was with a 2nd bucket/container. YMMV. Good luck!
