Utility module - user defined shapes

I was reviewing a structure model with the PM and showed him this:

expressing how the exterior girder cant was handled to chase cross slope of roadway.
His response was “yeah but the ends are supposed to be parallel to the abutment face.”
similar to what is displayed here:

My response was that there are limitations to my detail ability in TBC.

My question then - is there a way to create this offset angel face in the user defined shapes? to date i have been content with the squared face - knowing that it is only mostly right.
I can go to another software and make the detail ifc to reflect actual, but curious if it can be done in TBC

this is not possible today in TBC - until we can make these objects editable by exploding them into 3D faces or similar or until TBC provides tools to manipulate solids - it is possible to do for sure in the future.
