Groups and subgroups on inventory

Groups and subgroups on inventory

Can you make subgroups of subgroups etc. Example below. Camera being a main with dome being one of several subs as is IP one of several subs of the dome. Then you get to the 3meg, 5meg and 10meg being the acutal items. We sell a lot of product. This comes in handy when you are doing a quote . An assembly is not quite the same because you are always using the same items to build a system.
