BOM control/process between mechanical and electrical

So we're currently using only Electrical 2D and regular Solidworks 3D for design. This ends up in parts being called out twice, in mechanical prints and electrical schematics. What is a good method to send a BOM to our purchasing department that has no overlap, works with both Solidworks 3D and Solidworks Electrical 2D?
