I wish there was an option to manually save as well, since the game doesn't always Save on each day, so I would have done a lot of things on Friday but messed something up a route and would reload, only to be put back onto Thursday again since it never saved on Friday.

It's planned but since the game is custom made in unity, we have to code it all from scratch so it will take some time.
But eventually we will add a "save anywhere" solution.
