System Preferences, Energy Saver, Schedule, Are There Mods for this?

I'm running OS 10.10.5. I use the System Preferences, Energy Saver, Schedule setting to turn the machine on, on weekdays at a certain time, and then turn it off again after a function has been performed automatically by a start up program. This works really well. However there are days that I'd like to schedule two or more on/off cycles. I've searched the web, this site, and the app store for solutions and have not come up with one. Does anyone have any solutions?
