Well I don't quite know if anyone is interested in this, but someone over on the reddit page asked for this so I slapped it togheter and he's quite happy with it. So who knows maybe someone else needs it.
The premice is simple, adds a command to the main menu that calls an empty map of your choice and run a chosen common event id. There is 2 drawback tho, it does not load any save data, and you have to add a script call in your common event "Scene_Manager.push(Scene_Title)" // without commas // to return to the title screen after.
Anyway it's nothing fancy but it works.
