Do you know you don't have to report each transaction if it meets certain criteria - See Instructions for Schedule D, page D-11, column 3 :  Lines 1a and 8a - Transactions not reported on Form 8949

I have client with same situation - hundreds of stock transactions.   I only have to enter a dozen or so that are wash sales.   The rest meet the requirements per Sched D instructions that can be entered as lump sum on Schedule D.    It is a huge time saver.
