I made an account and enabled "Leaderboard" charts, does this mean I can never use cheats again?

I enabled Leaderboard charts and made an account and everything on my MAME cabinet. However, I now noticed I can no longer enable cheats in some games like the Mortal Kombat series. The cheats worked fine before this. 

I am assuming this is because we don't want cheaters to have high scores on the leaderboards. However, there are plenty of times where I am playing by myself or with a friend, and I would like to enable cheats. 

I thought the way LaunchBox handled it was I could choose if I wanted to enable cheats, but disable my score that session from the leaderboards. I don't see any way to do that. Can anyone lend me a pointer?

Also, if you HAVE to disconnect from the leaderboards in order to use cheats again,  is there any way to connect and disconnect in Big Box mode?
