sftp, kindle and calibre

[rajil.s]

Hi,

I am presently using email to transfer news from Calibre to the kindle every morning. I have two issues with that:
1. The ebooks land on the Home screen whereas I would rather like them to be in subfolder.
2. There is no way to delete them from the device rather than use "Moving to archived items"

I want to rather have them transferred to the device using sftp every morning. Is there any to force the device to come out of sleep at a certain time? I could then use a script to copy the ebooks everyday rather than using Whispernet.

Thanks
