How to see more pages on the membership plugin rules page?

Hi there -

I'm testing out the membership plugin and am using the rules function to include certain pages at certain membership levels.

The function will only display the most recent pages, about 10 of them. There's a little note that says, "only the most recent pages are shown above."

How do I get it to list all the pages on the site so I can cherry pick among older and recent pages for a particular membership level?

Thanks!
