Organizing object in the NLA editor?

Is (or rather HOW) it possible to organize the sorting of Object bars in the NLA editor?

I have a project with more than 40 Object bars in the NLA editor (most of them containing multiple tracks, containing multiple strips and actions) and I would very much like to have, say, all the Lamp-objects at the bottom of the Object Bars

  • so when I need to change some Lamp-properties I just scroll down in my NLA editor.

I am constantly getting lost in theses seemingly random ‘layers’ - I can’t even figure out by what system they are organized by the default settings.
