Adding a wait step before a lead goes into a stream
I have built an engagement program for leads that sales switches to a Marketing Re-Nurture status. The streams themselves are very straightforward. However, we want to wait a month before the lead receives any emails from the stream. I am having a hard time determining where to put the wait step. Here's my flow steps:

The problem is that I have been getting alerts that people are being adding directly into stream 1, not waiting 1 month.
I currently have no transition rules in any of the streams, I'm just using smart campaigns. Is this something I should put in a transition rule? I also considered creating a stream with no content that leads could go into and then after 1 month they could transition into the stream with content. It seems like a very simple thing, so I'm just looking for the simplest way to do it.
