This is true, but some brokers like TD Ameritrade and Fidelity ( and others?)

I use TD Ameritrade and found this out this year.
You either get tax software that allows this, or you fix the trade data manually,
OR
as suggested above you use the summarize option (no details) and attach a copy of your transaction details in PDF format, or mail it in.
