In the same way that we can manage availability and workflows outside the scheduling links so that they can be assigned to several scheduling links at the same time and have an impact on the links concerned when they are updated without having to edit the scheduling links one by one, I'd like to be able to manage my custom questions and my additional info globally and assign them to the links I want. Currently, if I update my additional info in a scheduling link, I have to edit all the scheduling links that have the same additional info (the same goes for custom fields). BORING!
