How to add custom sorting to AdvancedDataGrid to worked on grouped Data?

I have an advancedDataGrid that I need to add custom sorting to it which overrides the original sort! my sorting should work using a combobox to select ascending and desending from with a sort button! I know this is a bug in flex that its original sorting only works in hierarchical data and not for groupingCollection
the dataProvider of my grid is a flat data. however, in the UI, the user can add grouping to the AdvancedDataGrid. so I want the sort to work on grouped data!
let's say the columns are : country, province, city. population and there is grouping on country and province
so the sorting should do the following:
1) if the user does a descending sort on country: only unitedStates will go up and Canada will go down.
2)if the user does a descending sort on province: the order of the grouping of province will change to Quebec, Ontario, British Columbia
3) if the user does a soring on city: although this is not a grouped column, it should do the sorting on all the cities.

You asked

That example allows sorting even when grouping is on. (press the button "Group on xxx" buttons).
That's why I thought it could be useful to you.
