Fibo level: add a "save as my defaults" option?

 
Sometimes after I changed a fibo or expansion object, I didn't need the change effect my default settings, can you add a checkbox "save as my defaults" in the "Fibo Levels" tab?
so, when it checked, after clicking ok, the user default settings will be changed; if not checked, then it will not effect the user default settings.
 
You need to create script which will build Fibo with your own default settings.
