Form 2074 Question

[Daft Doctor]

Hi, I'm helping a non-French speaking friend to fill in his form 2074 for the first time. Simple question, he has sold more than 3 lots of shares in the year (all in the UK). There is only room for 3 transactions on the 2074, so does he A. amalgamate the sales to an extent, with a more detailed breakdown on separate sheet, or B. fill in a second 2074, or C. do something else?

Any advice taken at face value but much appreciated.
