BuildBot will let you save pieces of a build using the client sided duplicator feature. You can load the build using the server sided duplicator, then save it with BuildBot. You need to bind a key to the duplicate command in your options menu, then just overlap your ghost brick with the brick you want to hit with your "invisible duplicator" (usually the baseplate) and press the keybind. That way you have the build saved onto your client, and can load it either normally, or using BuildBot.
