dunno if it can but i fail to imagine how that should work - how does it
know about your domains at all?

the loaded zones can be a wild mix of forward and reverse zones, what
exactly should it replace

doing something with 10, 200, 1000 zones is where admin software has
it's place - in the backend i coded in 2008 i can write pure hostnames
of our own zone as value for A records

when generate a zone from the database wthis will be replaced by the
current ip in our own one and an additional button triggers "rebuild all
zones from scratch"

more or less one night the days back and maybe with the "virtual CNMAE
for A records" or however one will call it a second night and the reason
for that was, well, a ipchange for the whole network
