Sparky backup system - how to copy ALL of my settings to /ETC/SKEL ?

[bpr-323]

I wouls like to create a snapshot where ALL my current configs and tweaks (e.g. Chromium extensions, menulibre menu structure, etc.) are cloned when I create a new user during installation.  By default, Sparky Backup system copies only SOME of my settings.  How do I copy ALL of my settings for ALL programs to the /etc/skel folder before creating a snapshot?
