Is there a way to change the schedule of the plug so that any day of the month can be chosen. Right now it is just day(s) of the week. 

Here is what I am trying to accomplish and the reason for the request. A few months ago I took a trip and the internet service went out and the modem/route had to be turned off and back on. I now have my router plugged into a HS105 plug to recycle it manually and that takes care of the problem.

What I want to do is schedule the router to shut down for xx minutes and then turn back on for routine maintenance but I do not need that to happen on a weekly basis. I would like to be able to set a schedule for once per month, every 6 weeks or every 2 months. Is this something R&D would consider doing or in the alternative, does anyone have a solution. I am sure there are other examples where this would be useful. 

doing as an update to the plug or do you know of a solution that would make this happen?
