Hey John,
Thanks for getting in touch!
In Event Tickets and Events Tickets Plus there is no specific option like that.
One alternative solution / workaround could be to add this information into the ticket description field.
As an example, on our demo page “Basic ticket example” is the ticket description.
Or another possibility: with Events Calendar PRO you can set up so called Additional Fields for the events. The field title is the same for all events, the content can vary.
On the same demo page, below the tickets box you see information in 3 columns: Details, Organizer, Other.
The content in the Other column comes from Additional Fields.
Let me know if this helps or if you have any additional questions.
Cheers,
Andras
