Can this be done........

I constantly have the problem when I'm trying to install a plane and it comes to the gauges that with atleast half of them there are gauges with the same name but differnet file sizes. Since I don't want to ruin other planes I have I don't overwrite until the instructions tell me. So I' wondering if I can just make seperate subfolders inside the Gauges folder called -insert plane name here- and put the gauges in there. How is this done, and is it easy to do
Thanks for anyone who replies.
