[dnsdist] modify response ip address

I've read documentation, but, not being very familiar with lua, didn't
get some parts of it. And didn't find examples in documentation about
modifying response packets based on their contents.
My question is, is it possible with current state of dnsdist to spoof A
and AAAA addresses in response packets based solely on A and AAAA fields?
Dns query for some random domain (domain is really random, so I can't
regexp domain name) returns A x.y.z.[1-12] and AAAA xxxx:yyyy:zzzz::[1-12]
(radom ip from 12 possible for each type)
If response matches those addresses I want them to be replaced with some
other addresses q.p.y.[1-12]
and AAAA qqqq:pppp:yyyy::[1-12] (also randomly from 12 possible for each
If it's possible would someone mind to give at least a basic snippet of
code, that may realize this functionality, thanks in advance.
