That is what I do. 

You can use the 3rd parameter to save()
https://www.kamailio.org/docs/modules/5.2.x/modules/registrar.html#registrar.f.save
to harmonize on save:
save("location","0x00","sip:$au at you.domain.tld")

For REGISTERs and INVITEs you can check for specific allowed $rd and
rewrite $rd to whatever you use for save().

if(is_method("INVITE|REGISTER"))
{
 if($rd=="foo" || $rd=="bar")
 {
  $rd="foo";
 }
}
else
{
 send_reply("503","you got the wrong server");
}
