Is there a way to schedule downloads for off-peak hours? (Hughesnet user)

Our ISP allows a limited download capacity of 15GB per month, but allows another 15GB between the hours of 2AM-8AM. I would like to be able to download the programs during this time. If it were at home, I would wake up and start the downloads, but being at my office at work this is not possible. I have a download manager which can schedule other downloads for my computer, but downloading through the Creative Cloud Installer app eliminates this possibility. Are direct download links available? Or another solution?
