Honey as an ingredient in BeerSmith

I have plugged in the ingredients for a Nut Brown Ale recipe into Beersmith.  One of the ingredients is 2 1/4 lbs of honey.  When I hit the "preview brewsheet" button it has me putting the honey in the primary fermenter.  I guess my question would be: For any beersmith recipe that includes honey is that actually the best time to add the honey, and if not, when is a generally accepted "best time" (i.e. add honey at the very end of the boil, or with no more than 5 or 10 minuted left in the boil? :-\  In working with honey to make mead, the overall feeling in every forum that I have read is that raw honey could have quite a few impurities in it and that boiling the honey would help, get rid of said impurities. 

I usually add honey at flameout. The flavors and aroma are very easily cooked off.

I know people that add honey during the start of wort cooling when beer is about 180F.  Hot enough to pasteurize but not boil off all the aroma and flavor.
