Office Interop Get selected save path from recent folders

[egresovnik]

In Word 2013 I am hooked on event DocumentBeforeSave. When user wants to save document, backstage view is displayed with possible locations and also recent folders. After user selected one of recent folders, event DocumentBeforeSave is triggered. Where is the information about selected path stored? I need to display Save dialog(Dialogs[WdWordDialog.wdDialogFileSaveAs]) directly in this event, but first I need to know which path user selected. Otherwise default path is selected and it could be counfusing for the user.
