If there's availability in PS and D1 on transcon flights, you're eligible for both. However, if you're booked in main cabin and you use an RUC, you'll get upgraded to PS and you'll be on the upgrade list for D1. If you booked PS and you use an RUC, you'd get upgraded to D1. This was confirmed by a phone rep last week.
