Auto Save before Security Logout

I have a Security Logout that runs when the page has been inactive for 10 minutes. This works great except if the user has left a form without saving then all their changes are lost. I have one form, in particular, for blog posts which is super easy to get distracted by something else half way through writing and then come back and it’s all gone.

Is there any way to save a forms data before the Security redirect? Bonus points for having that same form open up again in the same place after logging back in!

Thanks,
Heather
