In the Rules there was the option “When - A customer replies to outbound content”. 

This is not available in the workflows. It is only partially available where you select “Client- Has replied to post.”

where you need to point out every post, by name.

While in the rules it was for all posts, situation that helped a lot with the assignment of the responses to the posts.

It would be much more useful to have the ability to assign the conversation if the client responded to a post is “true” instead of having to add multiple audience rules for every post.

Below, I have added the example from the old automations, as you can see it is very simple, it handles all the Posts.

And the workflow version where we need to point to every post that we want to include.

So in the end it is not an idea, basically it is a request to import this option from rules to workflows, as it was very useful. 

Thank you.
