ProductScope AI Questions

Pls check if there is a bug or something, thanks

Can you add a new background category for automotive? One that has backgrounds with sports cars, classic cars, trucks, SUVs, and other vehicles?

It appeared to give amazing results but i have not checked them practically. I hope that they also would give amazing results.

My questions are:
1) I currently have my listing on amazon UK. So it asked me to first run chrome extension so that it captures the data and then i went to product scope AI page, all the listing information is there which i can tweak using "Rewrite for me". So the question is is this tool only applicable to already created listing and only to be used to rewrite to make it better?

2) In case it is applicable to new listing, then how can we use it to our newly created listing on amazon. I think, we may need to give a competitor listing for reference in that case and then use the revised competitor listing to copy to our listing page. Please confirm?

3) What can we do if the product is totally new and there is no competitor. Then will there be any use case. I think so by mentioning the product features, keywords and buyer motivations, it will auto populate the things. Is it so?

4) I am not that technical so kindly educate me on Subject Matter Fields and Back end search terms. What are they, importance and their usage on amazon listing
