Entering multiple capital transactions for same security on 8449

[RWG1950]

When a customer presents a 1099-B with a great many transactions (coded A for example) all for the same security, is it acceptable
to enter just the summary of its gains & losses as shown on the1099-B on 8449 for this security and check the box on schedule "D" and create a PDF
listing all the transactions? Would a PDF of the customer's 1099-B showing all transactions as an attachment to the e-file suffice for this purpose?
Was wondering how other preparers handle this issue. Thanks for comments.

You don't need to do any of that. You can even bypass 8849 and put amounts directly on D line 1a.

I'm not sure what you "must" do, but I have several clients with large numbers of stock sales in mult-category Schedule D transactions.
My software allows me first to create an entry for each brokerage account, then asks for details on each applicable category. Form 8949 then shows something like "ABC Brokerage Acct -123" with totals for each Form 8949 block, The information automatically transfers correctly to Schedule D.
It is a simple matter to attach the one-page brokerage 1099-B SUMMARY page to the efiled return as a PDF document.
Gone are the days of enteriing individual stock sales, unless you are a glutton for punishment. . .
