Embedding Additional Software or Customizations on Bootable Restore USB

I’m not familiar enough with some of the fancy filesystem overlapping and such (SquashFS and such) to make a judgment on how I might make persistent modifications to the UrBackup Bootable USB restore image.

What I want to do is …

I want to embed (for example) remote support tools into the package so I can assist clients with restores.

How can I do this so the settings STICK?

Is the USB already very malleable already and I can just make edits or does each boot-up get loaded into RAM and no changes can be made?

Any help with this will be greatly appreciated!

I’m familiar with Linux and such, but I want to know more specifically how someone else would go about this.
