Customizing Labels on a 4 Dimensional Bubble Chart

Hi,

I am looking for help related to labels on a 4 dimensional bubble chart that I am creating.
1) The labels on each bubble is represented by 'Team Name' and 'Headcount'
2) I need to separate these two labels, where the 'Team Name' is displayed right below each bubble, and 'Headcount' is displayed in the center of each bubble.

I am also sharing the excel file that I have created for this.

Any guidance/help will be greatly appreciated.

Thank you in advance!!
