Sorry for taking so long, been busy, I dont know if I understand but...In File->New->Conversation, you create the new conversation (duh) the way to make the conversation like that, with your right mouse button just keep clicking "Insert Line" or Ctrl+A.
In the "Dialogue" bar in the bottom you select you select who is the listener of the conversation and the listener and can adjust this with the "..." buttons, the owner of the conversation is the character you assign it to while making the .utc (the creature), who you assign a conversation to.
