Defaulting exposed variables when copying and pasting classes

I’ve created a class which has several exposed variables, some are changed automatically and are only exposed because these variables need to have any changes saved in the editor not just run time.
Some of these automated variables needs to go back to its default value when I copy and paste the class in the editor.
I was wondering if there was any way to automate that change? (beyond having a bool to automate any changes that need to be made)
