Unfortunately, the libraries do not support hierarchies. This means the library layout is flat and with fully qualified resistors, you end up with a long list of them:
.. R1206_910R_1% R1206_1k00_1% R1206_1k10_1% R1206_1k20_1% .. I don't have a satisfying solution. I never fund a use to the many possible fields. Especially the footprints are a mess as there is no link from the footprint to the schematic item. DXP provides that now by the way.
