Targeting a surface twice with an Inroads template

Good morning / evening / afternoon all,

I was wondering if there was a way to have a template target a surface twice when creating a component. 

I have a project where we're filling in part of a ditch between two embankments, but there's a small berm in the middle. Ideally, we'd really like to be able to target the ground with the slope coming off of the embankment, and then run a ditch a couple feet over and then tie back into the existing ground wherever that slope catches. A coworkers sent me the Bentley institutes end conditions course, and on one of the pages it had this image, which is pretty much exactly what we're looking for - which leads me to believe that it cold be possible!

That is on page 38 of the "Defining Template End Conditions" course by the Bentley institute for the 2021 release version of Openrail designer.

If you have any tips or ideas they would be much appreciated!
