You can create a new group of databases. Groups belong to a primary region. 
turso group create <group-name> [flags]
Creating more than one group is limited to Scaler, Pro and Enterprise plans.
Turso will automatically detect the closest region and use that as the primary region. You can override this by specifying the --location flag.
