The ability to Assign Superelevation to Approach Slabs would be good.

If I use the Sync with Deck that does bank the approach slab but also extends the edge of the approach out to the fascia of the Bridge. Typically, our approach slab extends only to the edge of the shoulder which is where the Edge of Pavement will be. We would also have curb hear for the Bridge Approach Rail so no slab under the curb.

Additionally, the approach slab is below finish-grade so the ability to follow super with say a -3" vertical offset would be needed if we need to add 3" of pavement.
