[Closed] ability To keyframe Listcontroller active controller

Hi Folks is it posible to set multiple controllers in a list active state as keyframable?

heres what I have going on take any object, assign a list controller. give it maybe 3 more euler controllers let say

when you set the controller you want as active it is non keyable. Even if you did it via script

$.rotation.controller.setactive 3 will set the 3rd euler as the active controller it just returns ok in the listener window. I am trying to swith to different controllers via a pushbutton in script which is easily successful except it remains no key frames when trying to animate.

Thanks for any help in advance
