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.
