Bulk update of sniffer channel definitions

Following a change in our server architecture, the IP for one of our major applications has changed, and as a result the PRTG Sniffer channel definitions are now wrong.

Is there a way to perform a bulk update of all sniffer channel definitions, or better yet some way of having all sniffer sensors inherit their channel definitions from a root object (I am talking about the IP/port definition of the channel, not the channel unit definition).

We currently have a relatively limited number of sniffers (about 15) but this could reach 300 in the coming year, and I'm apprehensive about future application updates...

Thanks, Jeremy Gibbons
