Allocating fixed IPv6 addresses to hosts with multiple NICs

Is anyone handing out fixed IPv6 addresses with ISC DHCP?
With IPv4 we hand out IP addresses based on MAC addresses ("hardware Ethernet" and "fixed-address" config entries).
With IPv6 we hand out IP addresses based on DUID ("host-identifier option dhcp6.client-id" and "fixed-address6" config entries).
Our problem is that the DUID is system specific and not NIC specific. To uniquely specify a NIC, I need to specify both the DUID and the IAID, but I can't find any way of specifying an IAID. This effectively makes DHCPv6 useless for us on systems with multiple NICs.
Is there a way of handing out different predefined IPv6 addresses to for different NICs on a host?
I'm hoping that I've missed something (obvious or otherwise). If not, I'll need to investigate alternate implementations.
TIA
