Automatically open last book when powering on.

I have searched all over the place for an answer to this. If it is on the forum it has eluded me and I apologize in advance if this has already been answered.

Is there a simple way I can modify my Kobo Mini to automatically load the last book I was reading when I power on the device?

I noticed that Koreader has this option but I can't seem to find an option to start Koreader on startup (which would then load the book).

I am pretty good with computers and programing so I am not worried about setting this all up. I was just wondering if there was a simple way of adding this feature without installing a bunch of stuff I probably won't ever use.

Ideally I just want the default reader to start automatically when I power on my Kobo Mini (and if possible go directly to sleep afterwards...).

Thank you!
