The use of
autosave would use the command
quicksave, which in the source is coded to use slot #1 all the time. In order to do what you are requesting, you would need to modify the source code to change slots. To do this, you would need Dark Basic Pro and the required plugins, and set your compiler to compile the version of the source you are working in.
There are no current
public mods available that have this feature. I only know of one private source that allows the
quicksave to use a different slot and allows for more than the default nine saves.
There's no problem that can't be solved without applying a little scripting.
