How to change titles in multiple posts in one thread

[Kamil]

A user created a post with inaccurate title. Every other user who replies to this post is in fact creating post like Re: A very inaccurate title of this great post. 

How can I edit titles of all these posts instead of editing one-by-one?

@Kamil- You must need to edit every post title for this. However, you can edit the post title using rest call in one go.

There would be two calls, one for the main thread (A very inaccurate title of this great post) and one for all the replies (Re: A very inaccurate title of this great post) and you will need to loop through all the replies to update the title.
