For each Google Calendar account there is a default calendar, but the user can add more calendars for example: Family, School ...etc

I synced my Gmail account with evolution and it asks me whether I want to also sync Google Calendar and Google Contacts. I checked them, but I found that it only syncs the default calendar ignoring the rest of my calendars.

Why it does not sync the other ones automatically? And how to do that manually if it is impossible to be done automatically.
