Well it is possible to have blend update by the history mechanism... If you do something that changes the surface on either side of the blend, the blend will recalculate itself without you needing to undo and redo it separately. That's usually only if you do your edits right after the blend has been created before doing any other trimming, boolean, or joining operation on the objects though.
