There is a rule in Surveyor that can be added that will give you the DCC/HUD option. I've done it, but I can't remember which one it is. Some one will probably come up with it.
Edit: I found a post I made over as year ago about this. Some one was asking the same question. Here's my post.
"Try this.
Open up Surveyor and load the session you want to run in DCC.
After it's loaded, Click on Menu in the upper left hand corner. Click on 'Edit Session'
When the Edit Session window opens up, Click on Add. Look for 'Control Type' in the list that appears. Highlight it and Click on the green arrow. Click on the green arrow again, and the 'Edit session' window will disappear.
Go back to the Menu and Click on 'Save As'. When that window opens up you can add DCC to the title if you want. Click on green again and close out Surveyor. If you want to, you can Click on 'Save' instead of 'Save as' and do the same thing.
Open up Driver. Your original Session with Cab Control will still be there and a new Session with a 'C' should also be there. Load it and you should be good to go with DCC control."
