Can I link to a specific submission

Can you be more specific on what you're trying to do? You can't link to a specific submission per se, but you can use the EDIT SUBMISSION LINK. This link will open the form with the filled out values from a previous submission.

If the intention is to let your users access to that specific submission they previously made, the guide below should cover that.
