[otrs] Adding the TicketType-field to Answers

Hello list, similar to the post "Adding the Services field to the close tab?", we'd like to get the possibility to change the Ticket Type by answering Tickets. We've already realized it in creating notes, but it would be great to change the type in one step by creating an answer and changing the type. I cannot find such entry at Ticket -> Frontend::Agent::Ticket::ViewCompose Do I look at the wrong place? Any hints would be great Using OTRS 2.3.3 with ITSM 1.2.2 Thanks in advance Markus Nagel
