Hi, yes, but you would need another plugin to add it to the menu. I have [CGMZ] Menu Command Window that lets you add custom commands to the menu. If using that, you would make the name/symbol whatever you want (not blank) and then for the JS you would put:
SceneManager.push(CGMZ_Scene_QuestSystem);
There are also other plugins that can add custom commands to the menu, but I do not know how they work as I only use CGMZ plugins.
