I filed one Form 2555 and rather than fill out the dates on Part III of the form, I attached an explanation of my two periods of physical presence abroad that listed all the dates in each country for these periods, and used both periods for calculating my number of qualifying days abroad. My CPA agreed to take this approach, with the caveat that the IRS may or may not accept this position.
So far the IRS has accepted my return and issued my refund. I think they have 3 years to audit me so I won't really know I'm in the clear until then.
