1099-B can't be imported from pdf

Why can't a 1099-B be imported from the Consolidated Tax Statement? 1099-Div work fine. But B's need to be entered manually (which is ridiculously confusing for me). The docs are available from my broker but they aren't able to be automatically imported to TT yet. This also goes for people who would rather not give their log-in credentials out (which they really should change after their taxes are done BTW). Turbo Tax needs to offer the ability to upload the pdf of 1099-B to their customers.
