Problem Description

AECOsim Building Designer specifies the following dgnlibs as sources for Drawing seeds:

C:\ProgramData\Bentley\AECOsimBuildingDesigner V8i Ss6\WorkSpace\BuildingDatasets\Dataset_GB_Mod\dgnlib\DrawingSeed_Architectural.dgnlib
C:\ProgramData\Bentley\AECOsimBuildingDesigner V8i Ss6\WorkSpace\BuildingDatasets\Dataset_GB_Mod\dgnlib\DrawingSeed_General.dgnlib
C:\ProgramData\Bentley\AECOsimBuildingDesigner V8i Ss6\WorkSpace\BuildingDatasets\Dataset_GB_Mod\dgnlib\DrawingSeed_Structural.dgnlib
C:\ProgramData\Bentley\AECOsimBuildingDesigner V8i Ss6\WorkSpace\BuildingDatasets\Dataset_GB_Mod\dgnlib\DrawingSeed_Mechanical.dgnlib
C:\ProgramData\Bentley\AECOsimBuildingDesigner V8i Ss6\WorkSpace\BuildingDatasets\Dataset_GB_Mod\dgnlib\DrawingSeed_Electrical.dgnlib

Additional MS_DRAWINGSEED_LIBLIST values can be set to add project or site specific seeds e.g.: 

MS_DRAWINGSEED_LIBLIST > $(PROJ_DATASET)dgnlib/Project_DrawingSeed_Architectural.dgnlib

This currently results in duplicated entries in the callout tool settings;
