How can I create a poll with photos put in subject categories, such as Landscape, Portraiture, Monochrome, etc., please? I don't want to create a separate poll for each subject. The "category" facility on PollUnit seems only suited to vote on technical, composition, impact and other facets within a photo.
This is not (yet) possible. We have planned this feature in the future and we can put you on the notification list if you want?
