At 7 Maxwells Green Somerville, MA 02144, there are 3 entrances: 1) front door, 2) back door, and 3) garage entrance. Only front door is accessible from Maxwell's Green road, because Somerville blocks the road from Maxwell's Green to Clyde St (see the barrier pointed by the red arrow in the attached picture). Waze always routes me via Maxwell's Green road, even if I want to enter the building from garage door.

I was trying to add 3 entry points to the apartment to get the right route when I am entering the building from garage door, but all got deleted. I am not sure why. In addition, the direction from Maxwell's Green to Clyde St and vice versa should be blocked to make sure Waze provide a right route. Otherwise, even if I set my destination to 56 Maxwells Green as a workaround for me to try to get the right routes to the garage entrance, Waze still uses Maxwells Green, giving a wrong route.

Thanks in advance for your help.
