Can we specify order of CustomShadowVariable listerners?

for example,

@CustomShadowVariable(
variableListenerClass = MyVariableListener1.class,
position=0, // the first listener to call
sources = ...)

@CustomShadowVariable(
variableListenerClass = MyVariableListener2.class,
after=MyVariableListener1.class, // set the listener2 after the listener1
sources = ...)

So we can specify the order of multiple listeners by "position", "after" and "before".
