How do I set SkyDrive automatically to only sync during off work hours, such as only between midnight and 5am so as not to slow internet access to my working computer?

I have three computers syncing that share the same internet router and when they are syncing everything else slows down.  I would like to set the times that SkyDrive syncs to be limited to off work hours only, such as midnight to five a.m. and week ends.  Since I am using SkyDrive primarily as a back up and storage service timely syncing is not required.  I know I can just shut off syncing and then turn it back on, but I would prefer not to have to do this on each computer, but rather have them set to do it automatically at the times I have preset.  I don't see an easy check box for this as I have on some other services.  Please advise.
