Status map icons

Hey guys, new to the forums here - wondered if there was a way to assign icons to the items in the status map? Looking at screenshots it looks like theres a way but I’ll be darned if I can find it. I’m assuming that you’d assign this variable somewhere under either the individual hosts.cfg entry - or the hostsgroup.cfg entries - so machine X is represented by icon 1 in the map, or members of hostgroup A are represented by icon 2 or somesuch.

Thanks all.

its in the hostextinfo section of the objects definitions.
