Dynamic URL generation in menu

Anyone know how I can make a menu item that is dynamic?

Basically I want to have a link under "My Account" that links to a page created by the user. Each user will have a link to their own content, not other people's

Any suggestions on how to go about this?

I am using the "Unique Field" module to limit the number of nodes created by any user to 1 and want the menu to link to the user's page
