Can you somehow send DDNS update twice for zone?

Hey, hope someone can help or at least tell me its not possible because im
going crazy already :) 

Here is the scenario. 

Im runing both DHCPv4 and DHCPv6 server, v4 is serving local IPs and v6 is
serving public ips. Both are currently updating in to lets say
lan.domain.com and everything is working as it suppose to however i dont
like that if you resolve host from outside (lets say test.lan.domain.com)
you will get local A and public AAAA record. So i decided it would be good
to split configuration in bind in to internal and public view for that
doimain. In internal view resolving hosts in lan.domain.com would give both
A and AAAA records, but in public view you would only get AAAA. However here
is a problem, to get this to work i would need to somehow convince dhcpv6
server to send AAAA record update TWICE, one for public and one for
internal, however since its technically same domain i cant find combination
that would work. I tried adding 2 ips in to primary, in hope it will update
both primary and i can separate them in bind with proper matching key/ip,
without success, i tried double zone statements with different key/primary
combination, no luck... 

So bottom line, is there a way for dhcp to send dns update for same zone
twice? Or i guess other option would be to somehow pass update from one view
to the other in bind...
