About Folder List Issue

Hi,
How to show dashboard total number on Grafana folder list or dropdown list ??
ex. folder_A (2)
folder_B (3)
folder_C (6)
…etc
The 2 was dashboard total number on this folder_A.
The 3 was dashboard total number on this folder_B.
The 6 was dashboard total number on this folder_C.

Thanks
