Generate a first draft return?

I use Generate a first-draft to help me get started writing chapters. I tend to forget to copy/paste my instructions to Sudowrite to Word doc or Notepa. Sudowrite then generates a first draft and I go, oh, that's not what I wanted, but there is no way for me to go back to what I wrote and modify it (unless of course, I saved what I wrote). It would be a nice feature if I could just hit the back button and go back to my original instructions. (Did I make this clear? Hope so.)
