Yes. When you see a Fact you want to bookmark, click on the flag in the toolbar at the top of the screen to add it to your “My Favorites” list. Your personal “My Favorites” folder is one of the options on the first pull-down menu to the left, so you can go here at any time.

If later you decide to remove a Fact from your personal folder, simply click the flag and the Fact will be removed from your “My Favorites” list. Isn’t this a great way to keep track of the Facts you need to hit harder?
