Would it be possible to increase the maximum delay for Spool with Time Delay?

Here's the context: I have to do a lot of printing this time of year on an Epson that's a bit clog prone. I'm going away for a few days, and would really like to have my printer ready to get back to work when I get back. I think printing an Unclog Pattern 2 or 3 times a day would be an ideal way to keep the ink flowing smoothly, and with the option for spooling with a time delay I thought I would be able to manage it all within QImage.

Unfortunately for this plan the maximum delay is just 120 minutes, 59 seconds. Would it be possible to increase the maximum delay to 8 or 12 hours?

Thanks,

Drew
