When setting filters for a Set there does not seem to be an option to filter on the Template used to create the Object.
Add a built-in Relation “Creation Template” and put the name of the template there (preferably as link so that reference is updated when the name of the Template is changed)
I have a single Object Type that I want to split over different Kanban views, depending on the Template that was selected when I created the Object.
I could manually add a Relation to differentiate the Objects, but who likes to do stuff manually?!
