host-uniq

hello,
I’d like to know if is it possibile to set a specific host-uniq tag for the PPPoE client.
Vodafone Italia only works with the Vodafone Station Revolution, a not so good router/VoIP gateway.
someone found out that is possibile, although not officially, to replace the VSR with a generic router (Asus, Edgerouter, DD-WRT) setting the host-uniq tag to the Vodafone Station’s serial number.
hence, it would be great to be able to do the same thing with a mikrotik router.

thanks.
