Using SharePoint 2013 enterprise on-premises.
Last week a user recommended changing the 'show field' value from the default to 'Account' on our task lists. This is hundreds of changes as we have 220+ sites (and growing) so naturally I'm looking at PowerShell to accomplish this. I'm not clear on how to set the 'show field' value once I've gotten my reference to the column.
$column = $List.Fields[$ColumnName] $column .. ??
Hoping that someone here can show me the way on that.
