Change Redirect of Add Button on Embedded Report

Change Redirect of Add Button on Embedded Report

Hi - 
I have a report embedded on a page.  When I click on Add, it opens a new form within the small report window.  Is there any way to redirect this to a popup off the page so that the full form is visible?  I tried creating a custom function but there does not appear to be any way to add that to the menu bar of the report near the Add button.
Thanks.
