Hi Duce1147,
The list view of the Portfolio Editor can be sorted by any displayed column, and you can choose which columns to display. See "View / List Columns..." or right mouse click on the list view header and choose "Customize...".
Notice one of the column headers will be displaying a sort arrow. You can click on any column header to sort the list by data in that column. Click it again to toggle ascending/descending.
You cannot however order the list items arbitrarily, they are only listed in whatever sort order is currently set. You can however list investments in any specified order in a Report. In a report if you list by investment, and sort the report by
investment stack (order), you can manipulate the stack order however you want. See "Investments / Order..." from within the report window.
