Bulk Changes or Rule Implementation

We are running the eval currently and I have a couple of quick questions:

1. Under Quick Configuration Wizard, I would like to catagorize more than just Desktops and Servers from that screen. I have routers and switches being added as workstations and SNMP is enabled and working for those Routers and Switches.

2. Where can I find additional icons for brands? We have Asante switches and Apple & Novell Servers. If you add a Windows server you get a neat little icon. I want a neat little icon to differentiate those servers visually. Can I import images? Create a device type and image?

3. I want to be able to bulk change properties on items like routers, switches, servers, etc. How can I accomplish that?

Thanks,
David
