Layer Folders?

Hello everyone,

I would like to organize my layers a little so it is a little easier to understand when others are using/viewing my autocad drawing. 

I work with Photoshop a lot and in Photoshop I can make layer groups/folders. All it is is a folder that I can drag and drop layers into and then I can expand or collapse the folder. I am looking for this functionalitiy in AutoCAD. I played with the filters a little, but I don't want to make a filter to group my layers by, I would prefer to do a drag and drop method at my own discretion and not by some filter that I set. 

I will be honest that I havent done a lot of research on the filter system, but I did some quick google searches and messed with it for a little while. It didn't seem to give me the results I was looking for, but if that is the only way of grouping layers I guess I will have to do some more research on how to properly use that feature.

Thanks,

Nicholas
