My company hosts numerous webinar series with distinct topics every week. Feedback from our customers is they would like to know the weekly topic (and description) for what is being covered that week in advance, so they can decide to attend or not without having to join the webinar to hear the topic. Unfortunately, the only option to provide this to our customers is to manually change the series title week over week, which just isn't scale-able as we have many series.
Adding the ability to customize the title and description of the individual webinars within a series would help attendance and adoption. It would also be a better use of our customer's time as they would be able to plan to attend the webinars that add value to them.
