Sort the conversation with newest at the top

Hello this is probably very simple but just not seeing it as a option.  
I can sort the inbox so that the newest email is on top.   But what I am looking for is a way to sort the conversations/replies from the customer or the team, once I open a email thread.  
Currently if the team adds a internal message.  I need to scroll through the entire thread to the bottom in order to see it the most current reply.
