[CentOS] C7 : Firewalld

Being a fan of IPtables and dreading the eventual transition to Centos
7, I wondered if in C7's firewalld an interface can be assigned to a
single zone or to multiple zones such as 'private' and 'trusted'.

For example interface em1 having both trusted and public zones assigned
to it. If multiple zones per interface are permitted presumably one can
segregate traffic by IP range ?
