Using Script with Restore

[Macdelf]

Moode is a most wonderful piece of software. In addition I have some of my own enhancements (custom radio, IR files, play indicators, and an audio recorder). Because the team keeps it up to date I routinely run a script to invoke these things upon each update.  I know that the script can be added to the backup, but mine first requires the download of multiple files from my PC prior to running the script. What I do now is flash an sd card, boot the pi, install backup from the old version, use SCP to dump some files onto the pi, and finally run a script with SSH. 
If I could somehow get those files onto the pi prior to first boot, I could use the script function of restore. Is there a way?
