I would like to make it so that on one page the player has multiple links to click, all of which lead to the same page. When I try to do this I get a message that 'Item Page# already exists in this list'. Any way around this, short of duplicating the target page?

You can do this with the text processor. Add this to the page description:

{page:Page2:This is first link}
{page:Page2:This is second link}
