Add book to series please

[Valentin]

This is a collection of Doomsday Clock #7: Blind Spot, Doomsday Clock #8: Save Humanity and Doomsday Clock #9: Crisis, the single issues 7-9.
Can somebody add this as a non-primary work to the Doomsday Clock series (https://www.goodreads.com/series/2158...)?

Thank you very much!

[Sandra]

Done.
