How to restrict subject area access in a duty role?

Created copy of "Absence Management Transaction Analysis Duty" role. Want to remove "Payroll - User-Defined Tables Real Time" subject area access in this role.

Content (required):

We have created absence dashboard for our managers using Workforce Management - Absence Real Time and Workforce Management - Absence Calendar Details Real Time subject areas. We have custom abstract role for managers where I have added "Absence Management Transaction Analysis Duty" so that these subject areas access is granted to them. However, the "Absence Management Transaction Analysis Duty" also inherits "Payroll - User-Defined Tables Real Time" subject area. We don't want managers to have access to this subject area. How can we create a custom duty role where we can restrict access to subject areas.
