Option to not concatenate category labels in scatter chart

Hi,

When choosing to show category labels in scatter chart, whenever the user drills down into a category, the next level labels concatenate the selected category with the new level. For example, if user drills down into country US, then the states bubble labels will show as US Alabama. However, we would only like to see Alabama, because when drilling down further the labels become very long.

It would be good if there is an option under Category labels to select if you want to concatenate them or not while drilling down.

Thanks!
