Create zonefile records on GTM using TMSH

Gents, I know that this isn't exactly what you're looking for, but if you're handy with iControl, you can add a second step to your plan and write/run a script that will change the SOA values for you. Check out Management::ResourceRecord::update_soa in the iControl wiki. I use scripts to add/delete/modify A and MX records now instead of the GUI.

Even with the initial development time for the scripts, I've saved countless hours by not having to use the GUI. I can provide code samples in Perl because that's what I write in, but any other language and you're on your own.
