How can i duplicate this menu item

I need to duplicate this because I need other album categories(it only has the one music album page), like demo english and demo spanish. I'm not the most fluent in php so it has been a challenge to say the least. I was thinking that I would be able to copy and rename the files and item name however it looks as they are inserted when installed, which means I would have to make another install which would have to be a different name and seems like a nightmare. please advise.
