How to save the post processing scripts configuration with Cura?
I'm a Simplify3D user which allows one to save "factory" files. It appears that Cura supports printer profile configuration and saving.

From the above link, one is directed to enter the profile manager. You can duplicate an existing profile and rename it to separate it from the protected (standard/stock?) profiles.

Without using Cura to confirm this, I suspect that you'll discover this may be the solution you seek.
