Work on multiple discrete change requests simultaneously

[jchatfranklin]

Placed this in the "How To" as well, in case I've missed the answer:

Here's what I want to do:

Open a change request. Change 5 pages. Send this change request to Reviewer A.
Right away, open a new change request. Change 5 different pages. Send this change request to Reviewer B.

Each reviewer should see and be able to comment on only their respective changes, i.e., Reviewer A should receive ONLY his changes, and Reviewer B should receive ONLY her changes.

Then I can merge each set individually, as well, once I've incorporated feedback.
