Why can't you include a custom toolbar item on the parent view of a Tab? I got around this by inserting a bespoke item at the top of my list template to represent the action that would have gone in the toolbar item, and then on all subsequent child views I display the toolbar item as intended. This works, but it feels a little clunky. Any guidance here? Thanks!
