I'll add my voice to this. Currently I build a trend view in Excel. The
benefit of this vs the marketing channel is for clients that don't or
cannot setup to use that report. It's a more automated solution.
I would add that we need to have access to the user agent string within
DW as a part of this request. While the roll-up stuff is nice, sometimes
you're trying to trouble shoot something, or have such a specific
question, that you really need to have access to the user-agent string.
This really came to light while doing some analysis on the Google
Preview traffic that is now appearing.
