Map not found Error while running a docker file in local machine

[pjw1]

Hi, thank you for your generous starter kit!

I'm using the newest Carla version 0.9.10.1 and I'm trying to submit your dockerfile to the leaderboard for test.
Before submit, I'm trying to run the docker file on my local machine.

When I set my ROUTES variable to routes_devtest.xml, it runs well in other scenarios, but it stops at RouteScenario_3 (Town 06), saying map not found.
I found Town06 does not exist in client.get_available_maps(). (the newest carla 0.9.10.1 seems to have only 5 towns, town01 to 05)

I want to ask that

1. is it ok to submit this docker file to alphadrive leaderboard? or do I have to add extra Towns (town06 to 10) manually before submit?
2. How can I add extra towns?

Thanks
