I know that there is option to create a new ticket on customer behalf creating the first entry of "message" type
What I need is almost the same but without creating a new ticket, I need to add a message (not reply) to an existing ticket as if it was sent (e-mailed or written) by a customer.
Currently, I found one possibility - write a reply and then hack (mod) class.thread_actions.php and thread-entry-edit.tmpl.php adding "poster" field to 'Edit Thread Entry' form. But I am wondering if there is a "hack-free" solution (plugin maybe?).
(Why I need this: as I wrote in another discussion, customers like to hit "reply" buttons in their mail clients and write something like "btw, regarding another my problem which we discussed two weeks ago...". So I want to move a customer's message to the appropriate ticket
I understand that I need to change entry->type from 'R' to 'M' and probably adjust other fields)
