Slopes on Cross-sections

Hi Guys,

I'm wondering if you can help...

We're currenly working on a design and build job, which consists of a number of Treatment Areas that need to be dug out and replaced because the existing road base/surface has failed.

Now, because some of these areas are small (40m to 60m) we don't have much space to transition to design cross-falls and back to existing, so we are forced to put our new construction to the existing cross-falls... So be it.

As we have to do this, I would like to put the cross slopes on my exported sections via annotation. I see the area in annotate cross-sections that I think would allow it, but can't get it to work. How do you guys do this? 

Thanks in advance for your help.
