Duplicated scenes and drivers configuration

After creating a “full copy” of a scene, in the same Blender file, I realized that all drivers of my characters were inactive, in the duplicated scene.
The fact is that, although all objects get some duplicated name like “armature.001″, the OB/Bone fields are linked to the orginal armature object’s name, and not the duplicated one.
So, do I really need to set up this field for all of my characters, AGAIN, for ALL DRIVERS?
Is there any way that I can simply fix the link for the duplicated object armature?
