Looking for Hide-Thanks alternative

[mp3president]

What i mean is this:

Now when you click thanks the "hidden content" will be shown.
Or, when you leave a quick reply, it will also show the hidden content.

What i want is this :

You click the thanks button, and the hidden content will be shown.
Automatically the board will also place a standard "Quick reply" message. (thank you for this post or something like that.)(ajustable in ACP)

Normaly the members can do themselve a quick reply and a message.
I want in parts of my forum, that they only have to hit the thanks button, but when they do that, automatically a reply message will be placed beneath the topic.
