[OR] Is there an equivalent to Point Density Interval in Open Roads?

I have a Terrain element that is being driven by a corridor, but I have to add some linear breaklines manually where the corridor tools cannot work. In Ss2 and earlier, I would have added these as features in the DTM and used the Point Density Interval to cause triangles to be formed at intermediate points along long, straight segments of breaklines. I am able to add features to the terrain element, but I don't see any way to enable a similar capability.
