Thanks for the reply. Yeah ACF is great and used ACF Pro in previous projects, but as I understand it that approach would only be good if we want to add input fields on the wordpress backend (i.e., add input fields to the events post type on the WP admin side). As mentioned we were exploring if it would be possible to add file upload fields on the front end community event submission form. Was thinking somewhere along the line of additional fields in the event calendar settings, but right now a file upload field seems to be not supported for that. Will maybe submit that as a feature idea to the UserVoice link you gave. Thanks anyway.
