I'm trying to capture the emails subject in the send log. Is there any way for me to do this?

To the 'experienced' community members: Not sure how to rephrase this any better. Maybe you could tell me what exactly is unclear so I can clarify. Yet I'll try anyway.

I created a send log Data Extension with the following Fields:

JobID, ListID, BarchID, SubID, TriggeredSendID, ErrorCode, view_email_url.

I'd like to add another field like, 'subject' which represents the subject of the particular email being logged / sent. However, I am unable to capture that information. It doesn't look as if any of the personalization strings can be used.

@Kelly-J-Andrews hints at the ability to do this in the comment on the this answer.
