IT would be beneficial to create more primary node roles and if not then give us the ability to specify our own with our own icons. Currently I am seeing many items where there is no primary node role that covers the device. Sort of like a Cisco VG202, which is an analog voice device. Cisco has a specific PowerPoint icon that covers this type of device. I would like the ability to add it myself to cover the items on our network. General primary nodes roles just do not work for everyone.
