excel mail merge database with link for individual attachments

Hi All, Hoping someone can help me out. I am using excel as a database for mail merge and would like some way to have a column with a link/path to individual attachments that need to go to each recipient. e.g the attachment is an invoice so the path would be slightly different in each row.

Is there a macro or similar that can be created for this.

thank in advance.
