Ability to reply to latest message in conversation

In Requests, only the "Forward" button is shown below your own messages in the conversation thread. Quite often we will want to make an initial reply of "we're looking into it, try _____" and then follow that up with a "actually, that won't work; after more investigation, try ____" reply. It would be best if the whole thread was kept in the email for requester. In my email I would go into the Sent Items folder and do a Reply To All from there.

You can choose to forward and then manually enter the email address and modify the contents of the email so it looks like a reply, but a reply button would be so much simpler.

Thanks,

Sam
