I don't think there is.

I can think of all kinds of horrible workarounds - iptables SNAT, shell 
script doing a config-change & rndc reconfig on pcs failover.

But in general I'd agree with what Tony Finch said - give some thought 
to why you're caring about these source IPs.

TBH having used pcs/corosync I'm really curious what your use-case is. 
It seems massive overkill for having highly-available DNS.
