Selective export of conversation

Often in a conversation there are very interesting answers to questions I would like to share, e.g. in LinkendIn. But there is a chat history I dont’t want to share, i.e. I want to share only the last, e.g. 2 or 3 questions and answers. This could be realized by an “advanced” or “selective” sharing where I select by checkmarks the questions and answers that should be included in the export.
