I have been waiting for this feature for a very long time and I am not sure why it hasn't made it to the light of day. It would be great if you could Data Reference parcels. So if I am creating a plan for a specific lot I could just DREF what I need and not the entire lotting. This would make it far easier to stylize and deal with parcels than using the current xref approach to parcels. I know you can label an xreferenced parcel but it just seems like this isn't the best approach in all situations.
