Chain actions and merge branches?

2 questions.

  1. How can I chain actions in the campaign builder? For example, I have a campaign and I want to send 2 emails, one after the other with a 1 hour delay between them. After I’ve added an email action, I cant add another action.

  2. How can I merge branches? I have a condition where both outcomes send a different email. I want to merge those back together so they both receive the same email next.

Thanks for your time!
