Possible to add overloaded constructors at runtime?

[zack-snyder]

I saw in the examples that you have to set all overloaded constructors at once.

state["ABC"].setClass(kaguya::UserdataMetatable<ABC>()
	.setConstructors<ABC(),ABC(int)>()

Is it possible to add multiple overloaded constructors with multiple calls?
e.g.:

state["ABC"].setClass(kaguya::UserdataMetatable<ABC>()
	.addConstructors<ABC()>();

state["ABC"].setClass(kaguya::UserdataMetatable<ABC>()
	.addConstructors<ABC(int)>();
