I've also added 9 maps of mine to my own personal folder. I haven't added them to the scenario folder in case you prefer them to not be included in the game or would rather modify them for a campaign.
Oh and have you increased the amount of .gom files the random map generator can use? If so, then I could add in some of my own goms I made years back when I first started messing around with the RMG. As it will be the entire RandomData.xcr, I'll add it to my folder, so the game wont use it by default.
