Hi, Pim.
Thanks for your question.
I appreciate your question and the desire to customize it for your use. However, we cannot provide such in-depth customization help, per our Scope of Support / Terms.
To answer your question, yes, it’s possible with custom coding. I can point you to tribe_events_has_soldout() and other functions available to you in this file: /wp-content/plugins/event-tickets/src/template-tags/tickets.php
You might also want to refer to our Themer’s Guide.
If there’s a code snippet you’d like me to put some eyes on or something else I can help you with, please update this ticket or create a new ticket if it’s a separate issue.
Thank you very much for your understanding.
If you need some coding help, you may want to ask your developer or reference our documentation and list of known customizers.
