Dell Boomi: How to add multiple attachments to one email

I trust anybody can offer assistance me with this basic issue I have with Dell Boomi.

I have an integration stream where I get a few archives from an occasion. I need those records sent to my email adress. But presently I get 8 sends, with 8 archives. What I need is one mail, with 8 archives joined. It appears so simple but I can not discover this in Boomi, or somewhere else online.
