   1. Select Accounts|Tax Code Changes
   2. Select the sold account
   3. Select No Tax Effect
   4. Select OK
   5. Repeat for all sold lots
3. Buy back total quantity with average cost basis and date of purchase to reflect the proper time period (i.e. over/under 1 year for long term or short term gain/loss purposes)
4. Sell new total lot.
   

Make sure you put a memo line for each sold lot and the new combined lot (i.e. selling to combine multiple lots into one lot - or something to that effect.)

It is very important to make sure the multiple sold lots have the "no tax effect" tax code or the sales will go on the Schedule D.
