[Plugin: WP Favorite Posts] How to use full url as opposed to postid

Hello,

Great plugin!

Certain pages on my site do not have an ID#. I can add an “Add to favorite” link but because there is no ID# associated with it, I’m not able to add it to my favorite list. I was hoping there would be an easy way to put the complete url instead of the ID#.

How would I be able to do this?

Thank you.
