3ds max collapse animation tracks

Mrfred

Is there a way in max 2014 to collapse animation tracks with all the tangent and stuff?

(see attachment)
If I select my top float_list controller I can see the result of my two float_bezier...I'd like to either lose the second controller or convert my float_list to a bezier float and keep the results.

I know it's possible to do it in maxscript, did it before but I lost my code and was looking for an other approach before rescripting the collapse process.

I found the edit->controller->collapse option in the trackview however this options "bake the tracks together" Even tho I only had few keys
