No.  It's not really possible with radvd.  Radvd's main purpose is to
advertise the network prefix(es).  A host can trigger radvd to send the
prefix, and radvd logs the link local address, but the host doesn't obtain
its address from radvd, only the network prefix(es).  The host creates its
own address, and verifies it's unique with DAD (Duplicate Address
Detection).  Radvd in unaware what address the host configured.

Additionally, a host can just wait for a periodic advertisement...  So a
host may receive the prefix info from radvd and autoconfigure without radvd
knowing about it.

DHCPv6 may do something like that (but that's a question for a different
mailing list)...
