iControl with A Record modifications in ZoneRunner (PowerShell)

Hi Guys,

Currently looking into using iControl via PowerShell to script out some A record changes stored within bind/zonerunner. I've got powershell and the snap-in's all running great but having some trouble tracking down how I might approach this. If I'm understanding the API ref / docs, seems like Management::Zone should do the trick, but it seems like I would need to modify the zone files by hand and force bind to reload? Am I missing something?

TIA!
