Is there any way to detect when the user changes the order the components int the feature manager design tree?

I'm aware that there are a lot of delegates regarding a assembly doc. Is there any one capable of notifying when this event occurs?

EDIT:

There is the DAssemblyDocEvents_FeatureManagerTreeRebuildNotifyEventHandler() delegate who notifies whenever the tree is changed, but I'm looking for a less generic event.

Thanks in advance,
