It is already the case that we give ramps names based on the destinations indicated for them on the Big Green Signs. However, such signs also exist for at-grade intersections, and it would be nice to allow these to be given as verbal guidance. It is not uncommon in some areas for these navigational directions to be far more prominent than signs for the name of the road itself, which would mean allowing Waze to say them would be a big help for drivers.. This could be implemented by allowing editors to give names to specific turns.

For example, the turn https://www.waze.com/en-US/editor?env=usa&lon=-115.50083&lat=32.79973&zoom=7&segments=505661547,505661549 could be named "SR 111N to Brawley", and the turn https://www.waze.com/en-US/editor?env=usa&lon=-115.50083&lat=32.79973&zoom=7&segments=63551041,63551051 named "SR 111S to Calexico".

I would note that in the competing application OpenStreetMap, such an ability has been at least nominally implemented since as far back as 2009. See https://wiki.openstreetmap.org/wiki/Relation:destination_sign for a description.
