Python API: Changing the order of shapekeys quickly Using the Python API, is there a way to change order of shapekeys quicker than using the operator bpy.ops.object.shape_key_move(type='UP')?

This operator takes a long time to execute (if you want to move a shape key up 20 times, for example).

Is there a way to perform this quicker?
Campbell said me on IRC that there is currently no other solution :


  this needs to be done at a C/RNA level AFAICS.
  
  RNA collections need to have a sort callback which Python can use
