No, when you go to process a label it knows nothing about what features 
have been rendered. I guess in theory you could add all the features to 
the label cache. I guessing that to do this you would need some keyword 
at the LAYER level to indicate that these features need to be added to 
the label cache, but nothing exists today that would do this.

You might want to open a ticket for an enhancement and paste the cotent 
of your message and my response above into it.
