Correcting a Mistake - Add New Title

I noticed a day later after trying to submit a new title that I made a mistake. I know that you can correct it afterwards before it's been added, but I'm wodering if there is a way to correct it without having to type everything out all over again? As I already exited the page, the info isn't saved into the Add New Titile page (however I have taken screenshots). Of course I can type it all out again but it's such a waste of time tbh. I think that if this feature of easily correcting something you submitted (a title or person) by it being saved in the Add New Title page somehow isn't available, I think it would be really convinient to have a feature like that.
