Get "impossible" selected values

[#1]

I am using a macro to get a full list of the selected values for all the fields in the current selection.

To do this, I loop through the array returned by GetSelectedValues like this:

set oSelectedValues = ActiveDocument.GetField("Field").GetSelectedValues()
for j = 0 to oSelectedValues.Count - 1
     sValueList = sValueList & ", " & oSelectedValues.Item(j).Text
next
sCurrentSelection = "Field = " & sValueList 

However, the resulting list does not include the values which appear in the Current Selection box but which are excluded (not possible) through the selection of other fields.

I cannot use ActiveDocument.GetCurrentSelections to resolve this, because it only returns something like "20 of 5000" instead of the actual values if more than a few values are selected.

Any suggestions on how to get those impossible values into the selection?
