XF 1.3 Thread Title / Post Title

Hello everyone, we are still finding our way around the new Xenforo forum. Overall the member response has been very positive.
One thing I cannot seem to find is how to set a "Post Title"
I know Xenforo is different to VBulletin ( our previous software) however when replying to a thread members could include a "post title " in their reply.

Is there a setting I may have missed, or is there no way to add a title to a post within a thread?

Many thanks for help :)
