Changing ID Parameter

Does anyone know how I change the ID parameter on an invitation link? Every time I go to change it, it just adds the new parameter on to the old parameter at the end of the link.

now the example link is

But note - this is just an example - when you give this to your panel provider (or use some sort of email merge) you should replace example_id with the tracking id (or email) for each outbound link.

so it becomes


Then you will be able to track each outbound email with survey completion/abandonment/non start etc.
