PowerDNS for reverse-DNS delegation – management interface?

Hello everyone.

We have our Powerdns-based DNS servers, currently used for domain DNS management.

We must also use them for reverse DNS management; we did a test with a small IP class, just adding the right records directly to the mysql database.
It works and it's easy … but it's not fast, also because you have to insert a dozen IP C classes … so 255×12 = 3060 records …

Is there a simple, fast and dirty tool for managing IP in Powerdns?
A kind of web interface with the powerdns mysql database, which can do such a boring job?
