InRoads v8i SS2: How to clean up Cut/Fill Transition?

I am using InRoads v8i SS2 to model an interchange. In many areas, I am using an end condition for a modified embankment ("false cut") that creates a channel like a standard/true Cut condition would but then puts a mound behind it. This is done in order to continue the cut channel through an area where we want to keep the roadway drainage in a channel to take it to a stormwater management facility. The proposed contours between "true cut" and "modified embankment" sections looks very messy.  Any suggestions on the best way to tie these two sections together smoothly?  (The "modified embankment" section is wider than the "true cut" section as it has the mound behind it.) 

Thanks in advance,
