Viewing Raw Data

I have played with HAT, and cannot figure out if there is a tool that lets you view the original doc that was received.  Maybe there is a way in the new Admin tool, which I have not found yet.

Am I overlooking something, or have the developers of BizTalk deemed it unnecessary/unpractical to save the original raw data.  I understand that it will take a ton of space to keep the original docs, plus the XML representation in the MessageBox.  The only way I can think to do it is creating a PassThru subscription, then use the times in HAT to find the message in question. 

I am coming from a heavy EDI background, and this is just something that we are used to doing.  When something is now getting passed as expected, or a partner swears that they are sending data in a certain spot, we must look at the raw data to figure it out.  Maybe this is something they are addressing in R2 with all the EDI enhancments.

 Thoughts, or suggestions appreciated.
