Reordering Custom Controls

Is it possible to reorder custom controls for a fixture after they have been saved?

The only way I have been able to do this is to edit the custom fixture recipe, then delete the fixture from your show and re-add it with the new fixture setup. That works. Careful though - if you have a Group that only has that one old fixture in it then that group gets deleted when you kill the fixture and you lose your scene settings for that group. I solved this by being sure some other fixture is in that group before you delete your old fixture.
