If you allow customers to submit tickets using the built-in “Ticket links” app, users can always set the value of any ticket attribute marked as “visible to customer”. It would be useful to make such attributes visible to customers, without allowing them to set the value — so they can see the value when viewing the ticket in the messenger or ticket portal.
For our specific use case, we have an external ticketing system that allows us to log actions taken on a ticket. I’d like to be able to share these actions with customers. The current workaround would be to serialize the action log to the “Description” field. But, I’d like to instead write this to a separate field, if possible, without showing that field when users submit a ticket.
