Our environment must not be configured to allow that. Looking at the screen shots in the link, there is no + Add blue test in the right hand corner of the Publish AnswerSets section. Thanks for your help though!
I will reach out to you on a separate email. We should be able to add multiple lenses in the project as well schedule them in automation.
Sometimes you may not see the option to create additional lenses if one of the step in a project has an error (it will show up with little red triangle) Or for some reason it is pinned to an older version of the steps.
I will send an email and we can sort out the date and time for a meeting if it helps.
