Investment Revaluation Worksheet not reflect all investment items

1

I have read through the guides for The Investment Revaluations , understand that is where you can adjust the values of your investments to reflect their current market value, typically should use Investment Revaluation Worksheet under Reports tab to calculate the figures, There are 3 columns in the worksheet, one of them is Calculated Realized Gain - this is recalculated realized gain, my questions where is the input of current market price for this calculation? I can get the Revaluation report for investment which has actual transaction (sell), but cannot get any Investment Revaluation for those investment item without actual transaction but would like to adjust the values.
