I don't understand the system well enough to format a proper update request.

There's an intersection near my office where left turns are time-restricted. I looked at it in the map editor -- the only button available is "disallow all turns", and it's grayed out. I don't know what level is required to make that kind of change, or if it's even doable. Or how to put a link to the location in the post. I'm pretty sure my level is 1.

The intersection is Ridge Rd and Colonial Springs Rd, in Melville, NY. Left turns are banned between 6:30am and 9am.

Waze frequently routes me through there, because it's an obvious shortcut if you don't know how rush-hour backup from the adjacent traffic light makes the turn dangerous.
