How to add a "pause" between each file in queue?

I want to upload all the files in a directory to a ftp server daily.  The number of files varies from day to day.  Is there a simple way to put a pause between the upload of each file?  i.e, after each file is uploaded, wait another hour before sending the next one in queue?
Thank you!

No this is not possible as it is uncommon requirement. If you just want to upload the same file (or a folder with files) every x hour, this is already possible:
