Yes, working on the boats just now, and plan to animate them too.
However with numbers or flags, not so sure. Currently the model is the wheel and the base unit ( in the pic there are multiple placed down). To have a different number on each would require a different texture to multiple meshes. I feel that for the extra expense, it will be best just to use your imagination.[happy]
Edit: although I could mark a section on the base unit as a flexible colour, and the colour can then be matched to the boat it (pretends) to control.
