How to export new verified links only?

I'm trying to get links to a domain which I've already gotten links for. Can I export only the verified links that are brand new?

Also, is there some way to only submit to a URL just once? I don't want to submit to the same URL more than once.

You can list verified urls (right click on project(s)->show urls->verified) and then export them there.

A submission is only done once to each url per project by default.

Can I only export the new verified links? Not the verified links that currently existed before posting. Can I make it remember what URL was already submitted to in the past?

when sorting by the date column, you can export only selected entries.
