Import Trimble surface file (.ttm) into OpenRoads

Question

Can I import a Trimble surface file (.ttm) into OpenRoads?

I did a quick check and didn't see the option. You could ask in the OpenRoads forum they may know better. 
 Here are the options I see for importing Terrain elements. 
 
 Searching the help only gives an option for Trimble Link.
