As per Christine's post ( IpMonitor: What We're Working On) this is item #4. At the moment one thing you can do is do a mass import of monitors using the export/import xml feature in the Systems Settings area of ipMonitor.
Keep in mind you will need to create devices first and then set the parentid of each monitor in the xml before importing so they are associated with the correct device.
This tutorial article is for an older version of ipMonitor but it’s mostly the same now other than the UI changes ( the export is on the menu bar and not in a drop down ) and requiring a parentid in each monitors config to indicate the parent device.
Hope this helps!
