Hi Dhairya,
Yes, most job allocation variables can be used in a dynamic audience, including derived ones such as 'Number of direct reports'. Simply use those in a dynamic audience rule:
For example:
Total number of direct reports: At least "1" person(s)
OR Total number of indirect reports: At least "1" person(s)
OR Total number of temporary reports: At least "1" person(s)
