When security description Type: is set to Bond then add a field near the bottom right below 'Yield to Maturity' that says 'Factor': and fill it with a default of 1. For anyone who doesn't know what that is they can leave it alone. For those of us that do then we can change it.
The formula using the field is simple: downloaded number of shares * factor * downloaded price /100 = current value.
(yes the price typically needs to be divided by 100)
