Presumably the op would only use macros where needed, ie dynamically assigned addresses.  So, for a pool of addresses 
assigned for DSL/Cable/FIOS subscribers, that pool would have forward/reverse set up.

Note: I am definitely not up on my IPv6 knowledge, so there may be a Really Good Reason(tm) that one should not do 
this..  However, I was under the impression that having both forward and reverse for dynamic IPs was a best practice..
