This is great for adding attachments to all ticket emails. Is it possible to add attachments for a specific event only?

I'm also looking for a solution to attach event-specific document !

@mariomelchor & @fabricelaborie - I'm sure you could create a custom field to pick a media item (or just get the featured image, for example) for each event (or use Events Calendar Pro's custom fields) and incorporate that into this snippet somehow
