There is not an official way to do so built in, but since you can reboot via CWIS on the Status tab, it would probably be simple for someone with a coding interest to build a tool that would send the same command from a PC daily at xx:xx time as a workaround.
For an official workflow it would need to go through what is called a FER (Feature Enhancement Request) through Xerox (Call for 2nd level and ask that a FER be submitted). There is absolutely no guarantee they would make one, but it is worth a shot if the feature is important enough to you.
