Do I have to set a regular Cadence?

[Anonymous]

After creating an engagement program and creating multiple Streams, do you have to set a regular cadence? I would like to send emails irregularly. For example, I want to send the first email on monday, the second one week later, the third two weeks later and so on. Is there a problem with changing the cadence after each email goes out? 

Note: I realize that you can accomplish this with the old smart campaign flow but prefer to use the new engagement program so I can easily add new content and have multiple streams in the same place.

That's what I did.

But it seems like what you're talking about is adding a smart campaign with only a wait step in it, so that for one week's cast, you skip it and do nothing. Then the next week there's an email, then the following two weeks there are two more of these wait campaigns. That would give a bit of variance. Mine is more about randomness.
