Here's a quick workaround:
- In the Preferences menu, make a new list called "Favorites" (or whatever else you want to name it).
- Import the "Games" list into the "Favorites" list.
- Save it.
- Exit the Preferences menu and go back to the Front end.
- Rescan MAME (right click anywhere in the menu within the frontend while it's running and select "rescan")
In the frontend while it's running, make sure you are in your "games" list in MAME.
- "add" the added game which now appears in the games list to your "favorites" list. Do this by pressing the "6" button on your keyboard (Add favorite). A menu will come up. Hit enter to add it to your list of choice (in this case "favorites" or whatever you named it.
- Modify the name of the game in the in Preferences menu ("favorites" list)
Rinse and Repeat.
(P.S. - back up your MA directory before you attempt this, just in case)
