The software already has a system that was built to permanently save your settings. Just open any process that you want to save and click Save As New to add those settings into your profile database. Those settings are saved permanently in the file system and will be maintained regardless of what you do with the processes.
The processes do tend to change very frequently, so I would not recommend making that the only place that you save your important settings. For example, the Variable Settings Wizard, Multi Extrusion Wizard, Configuration Assistant, etc will all create, modify, and remove processes. The idea is that you create processes for the current parts that you want to print, so they tend to change for each print.
