How do I add multiple recipients to Smart Forms?

I've watched the video tutorial but as far as I can see, (using version 5.02) the dropdown menu for recipients only allows me to select a single recipient from the list of emails I've verified. Any help would be greatly appreciated.

Unfortunately Smart Forms can send only to a single recipient. But most email providers support filters, which let you automatically forward messages to additional addresses.

Much appreciated for the response Martin! I'd really like to see this as a function in future versions but for now thanks for the alternate solution.
