adding property while the bge is running? is it possible to add a game property to an object while the bge is running?

I realize you can access them easily enough, I am not asking about accessing properties just so that's clear.

I'm well aware that you can use a string as a list in the bge like so / which would be perfectly fine in most scenario's(and the same goes for dictionaries.) but I think it'd be more professional if you could physically add properties to objects in real time. 

    import bge
    scene = bge.logic.getCurrentScene()
    scene.objects['CentralControl']['L1']=str([(000.000,000.000,000.000),(000.000,000.000,000.001)])
print(scene.objects['CentralControl']['L1'])


postscript: this probably isn't important but i'm using blender v2.78a
Yes, that's possible.

Game objects behave like dictionaries, so you can just assign any value to any name (no need for adding a property in the Blender GUI):

scene.some_object["new_property"] = "Hello"


You can even store lists, objects and any other data type in these properties.
