Notes with circular border - vertical stacking?

Hi,

I am using notes (alphanumeric) with a tight fit border. There are instances where I need to add three such notes (i.e 5A, 6A, 7A etc) with tight fit circular borders and one single leader pointing to a drawing location. Just to clarify, these note numbers are dimension numbers. When I move the notes adjacent to each other, every now and then they snap vertically.

I am not sure why this is happening, but I would like it to snap horizontally. I tried stacked ballons, but that is not what I want. I am looking for the property in notes, that controls this snapping.

Any ideas? Much appreciated.

thanks,
