To enable the quantity in balloons you can edit the Table Properties and switch the Type to Quantity Split Circle in the BOM Balloons tab. I have multiple balloons I've created using "balloon note" and Creo places the leader on the bottom balloon and I'd like it to be attached to the top one.I have a very simple suggestion. Just create a balloon with a blank space in it. Using this video you can add multi leader dimensions and multi leader notes in Creo Parametric drawing.
