The Planning export names who is assigned

The Planning spreadsheet export has an Assigned column with the names of the people on each row.

Before this the file gave you a headcount and nothing else, so a plan you filtered by person came out unable to show who it was for. Each row names the people assigned to it, so an order with its work assigned further down stays empty and the names sit on the stages and components that carry them. The column is read-only, and imports ignore it.
