Geopak Drainage Profile - How to automatically show curbs/sidewalk etc

Running Geopak Drainage(SS2) 08.11.07.619

When I draw a drainage profile, is there a way to automatically display the curb and sidewalk? In the screenshot below, IN306S and IN306N are both curb inlets. Neither the curbs, nor the sidewalks are displayed automatically. Is there a way to prevent the profiles abruptly ending at the inlets, and instead go a little further outside? My existing and proposed TIN files definitely have data outside beyond the curbs.

Thanks,

Vinod
