Feature Request: Allow user to set expiration window (greater than 5 minutes)

[Abigail Watson]

Please allow the user to set the time of the software statement expiration window, or increase it more than 5 minutes.  The 5 minute window was a huge hassle for debugging, and delayed implementation by many days.  10 minutes might be a decent compromise.  Although selection boxes for either 5min or 30min would maybe be best.  

Thank you,
