Right now, I can modify the view, but see only some fields. I want to see my custom fields. It is much more important than the fields I am imposed, especially when creating segments. My goal is to filter by a field that is Campaign source, telling where I lead signed up : a lead magnet, an event, this way I could send emails relevant to what attracted them in the first place. Also, if I make changes in the available columns now, I can,t save it or at least having this selection appllied to other pages if I want to look at more pages of contacts.
