This dialog is available from the Edit / Symbol List... menu command when using the Advisor version of Fund Manager. This dialog is useful for making bulk investment property edits, for all investments with the same symbol.
Use this dialog to display or modify investment properties based on symbol. Select a symbol from the list, and the properties of this symbol will be displayed. Click the "Edit..." button next to any property to change this property for all open investments that have this same symbol. You can also use the "Add New Split Transaction..." button to record a new split transaction in each investment with this symbol.
