Hi. How are you? I understand what you’re saying. But that would be quite complicated to do given how the RPG Maker engine is built, since there’s no way to know if the user “saved the game” or which slot they used. That’s why the autosave slot is used, it’s made for cases like this where you can force a single specific slot. What you’re suggesting would require remaking the save/load manager, and that would be quite complicated without breaking other things. That’s why I went with auto-save, because it’s the most accessible in terms of possibilities and compatibility. Also, passing information from one scene to another is tricky without losing data, which complicates the matter even more. If it were something simple I’d be happy to give you a custom version of the plugin, but unfortunately this is more of a commission-level job than a straightforward update.
If I can help you with anything else, please don't hesitate to let me know. Best regards!
