To add to the recent reply to your question on BOM balloons, you can mix and match the balloons shown on the screen. Under table BOM balloons select alt symbol for the ones you want either triangles or circles. First you must create the triangle symbol, so go through the steps to create a custom symbol. On a circle around a note, that can be a symbol as well, but not tied to the BOM. In order to connect balloons to the BOM, the item must be in the repeat region, i.e. BOM.
