How do I create an automated email that includes all attachments at once, including a mapped doc?

Hi all,

I'm trying to figure out the correct automation settings to have one email sent that will include a link to all attachments. I have set up a mapped document and automated email for when a row is added or changed. Currently, I'm receiving two emails - one for the new row with attachment links and an additional email for when the mapped document is added to that row. Is there a way to receive all of these attachment links in just one email? It takes a few seconds for the mapped document to be added to the row, which is causing a second email to be generated.

Thanks for any help you can provide!
