No, I don't think so. For more authoritative details, see my post about this on the Bogleheads board:I went to my account and it looks like I can only enter this information in for brokerage accounts. Is there anyway to record it for mutual funds?

Actually, it is worst than FIFO, it appears they use average cost when you sell (I just refreshed my memory from my boglehead post), at least for external mutual funds. It is a really, really bad system and not at all obvious to the casual observer. Supposedly, they will fix it in the next couple of years.
Also, if you use Average cost for a single sale, you are locked into that system forever for that holding. It is the worst possible way to sell a mutual fund you have held over a long period of time and could cost your typical retiree a lot of money.
