Super Cruise Mapping Problem Reporting

There are specific areas where I have problems with Super Cruise. There should be a simple way to report the issues; however that does not seem to be the case. Has anyone found a good way to do this?

Two examples:

A section of I-26 NW of Columbia where the road was widened. Now Super Cruise will either not work or only in the left lanes.

Eastbound on Highway 74 in NC Near Columbus,  Super Cruise drops out every time I cross the bridge over the Green River. Works fine westbound and on Broad River Bridges nearby.
