Record counter for Always on Search panel items

Could we have an option to add a record counter to the fields that we select for Always On Search Panel in Search and Filter settings?
Example:

from this

· AC - Accounting Admin.

· AC - Billing & Accounts Receivable

· AC - Finance

· BK - Attorney

· BK - File Intake
to this

· AC - Accounting Admin. 56

· AC - Billing & Accounts Receivable 10

· AC - Finance 15

· BK - Attorney 100

· BK - File Intake 77
Or perhaps you can advise on how to write code for this
