Asset management

We are looking to extend our use of ServiceDesk Plus to manage our non-IT assets, furniture etc. I note that when editing an asset there is an option to add a collection relationship to a business service. I have looked for more information on this option in the documentation but it doesn't appear to be covered. Essentially what we are trying to achieve is to have the asset, for example a desk or chair allocated or related to a business service called furniture and then be able to report on all assets that are allocated to furniture and also all "service requests" on assets allocated to furniture.
Is that the intent of the relationship option or should I be looking at using static groups instead?

Regards,

Scott.
