possible to save import list as csv? and can increase import list more than 5?

1. Im able to put many items to the import list before import. but is there anyway I can save the import list to a csv file in case if I face issue with my site and want to reuse or recover or use the same list later.

2. I have noticed that on imporg list view page, I only see upto 5. is there any way I can increase the importlist view more than 5 per page? and can I select to import all at once?. now I see only the 5 items is importable at a time.
