Ghost 15 Scheduled backups do not wake the PC

I have scheduled daily backups at 10 PM.  If my PC (Windows 7) is in sleep mode at that time, Ghost 15 does not wake it up to do the backup - it just skips it.  Is there a way to have the Ghost scheduler function if the PC is in sleep mode?  I would prefer not to use Windows Task Scheduler.  Also without scheduling within Ghost, starting Ghost would not cause a backup to be performed.
