Our company use Forge Viewer to view Inventor drawings (IDW, DWG) in our solution for part ordering. User can select part by selecting item from BOM list as well by selecting balloon annotation in the drawing. However attached balloons are treated as single object in the viewer.

Please find attached an example for attached balloons:
