Copying entire category with Content Copier

Hello.

Is it possible to copy an entire category in Content Copier or batch posts for copying?

I seem to be limited to selecting and copying 10 posts at a time, which is going to take me forever. I have over 15,000 posts to copy.

Also, each time I click the next arrow to choose another 10 posts, the filtering and Additional Options check boxes for "Copy images" and "Copy terms" default back so I have to reselect them all every 10 posts.

Many thanks
David
