How do I start a new conversation thread without seeing previous posts on iMessage?

[iMore Question]

I text my friend and we have a mile-long thread of posts. How do we start fresh? When I click on the icon to create a new post it takes me to the bottom of the long series of posts to each other.

You could cc yourself thus adding a 3rd person WITHOUT actually adding a 3rd person and this should start a new string of messages, at least in theory.
