In “read messages” screen the headline includes only the last sender’s name

Hi

In “read messages” screen the headline includes only the last sender’s name.
That means for example if I sent a message to John Smith, than I will see “John Smith” in the headline, but if I was the last one who replied to him, than I will only see my name in the headline. That makes it very hard to find the messages that you are looking for.

Any ideas?

Thanks
