Modelers tend to collect a lot of different locomotives which can result in quite a "variety" of entries in DecoderPro roster listing. This can be especially true in a club setting where many club members may have roster entries. Having a way to create subsets of these locos that share some kind of commonality can greatly simplify management and programming of locomotives. Fortunately the developers of DecoderPro realized this and provided an option for creating groups consisting of subsets of roster entries. In this video I'll show you how to create these groups, add locomotives to them, delete them, and hide or show them. Once you give this a try I think you're going to like it.
