Corkboard

Someone on FB posted about using the corkboard function to plot her story, putting a few words on each index card and then shuffling them to see which order her plot incidents needed to be in and also where there were gaps that needed filling. I’ve already begun my story and am on Ch 3. If I use the corkboard as the poster did, then it alters the order of my chapters. Is there any way of using the corkboard as a stand-alone function without it affecting the order of the chapters, or, and this is the only way I can think of doing it, would I be better to open up a new project file and just use the corkboard function to plot the book?
