The spreadsheet pivot workflow no longer includes the old dialog for inserting selected static pivot cells. This removes an obsolete option now replaced by spillable pivots, simplifying the interface and reducing confusion for users.

The feature to reinsert specific pivot cells became obsolete with the new spillable pivots and ability to refer to spillable pivot cells[^1].
