How to limit choices on Approvals tile - want to remove Approve Payable Time option even though they

I have a department that is new to Absence Management.  Previously, all employees reported to the payroll clerk who approved the payable time during payroll.

Now, the employees report to their assigned managers so that absence requests can be routed and approved appropriately.

These managers also now have the Approvals Fluid tile that they never had before.  This is how they were taught to approve absence requests (they can also use the email link).  On their Approval tiles, they now also have the option to Approve Payable time for their direct reports.   It's only a matter of time before some other type of self-service request shows up on this menu.
