Starting a new 'project' with all new presets

I may be missing something simple here.

I want to create a complete set of new presets to use for a different venue - think a suite of sets for work and a suite of sets for personal.

I can not for the life of me find a way to clear all the presets to start fresh. I would have expected something in the left burger menu like ‘New Project’…

I am running the Windows 10 latest version.

Help?
