Retirement tax questions

Yes I know what Box 1c is for.  My brokerage statement shows me which assets are short- and long-term, which I can so designate in Turbo Tax; And my brokerage firm tells me the acquisition date is 'Various' for both short- and long-term assets, which again is an option in Turbo Tax (box 1b), so why is 'Various' not an option in Turbo Tax for date sold?  My brokerage firm fills box 1c with 'Various'.   I counted 213 sell dates.  Turbo Tax wants me to create 213 separate fields?  The only thing that is important is whether a sale is short or long term.  Why bother asking for acquisition and sell dates at all.
