As long as they weren't serialized, and if I used AD to do this, I would recommend MBd's recommendation of symbols. I think. I haven't used symbols before.

well you currently have 8 tickets on a page and turn of/ on every ticket separately?
 
so this can be enhanced
 
save a single ticket and than use this document as a placed document (go to document > place, this will place the ticket-document into your page-document, it is not linked externally but embedded into the page document, you can then replicate/dublicate the placed document) to replicate, https://vimeo.com/110134439
 
or use symbols https://vimeo.com/182383520
 
you can then edit one instance and every of the 8 tickets on the page will change 
 
cheers

In the Character panel, next to the Font control is a control that selects font categories. There should be a category for Missing Fonts. (Or you could close and open the document again.)
