Pro Forms: send email to different addresses based on the value of a dropdown

Hi, I’d like to conditionally send a pro forms email to different email address based on the value of a dropdown. Is it possible? I can’t find the way.
E.g. The dorpdown has a few different subjects of the email (Collaboration, Marketing, Events) and I want form with Collaboration will be sent to mailone@mail.com, form with Marketing sent to mailtwo@mail.com, …
Thanks
