[otrs] Config Item

Hi, On config item, you can create computers, and locations and the linked. So far so good. What I couldn't find how to do is to get a list of computer with certain characteristics on a particular locations. For example, under computers you can specific wheter it is a laptop or a desktop. How can I list all Laptops on Location 1? Or all desktops or Location 2? Thanks! Guillermo.
