Create a custom rule for roles delegation based in a hierarchical condition

Summary:

Hi,

The customer needs to create a custom rule for roles delegation that does not allow a delegation when, for example:

Director tries to delegate to Manager
Manager tries to delegate to Supervisor
Supervisor tries to delegate to Assistant

Due to legislative reasons when talking about working in another role with lower salaries.

The need here is to block this kind of delegation.

Allowing the delegation to proceed only when, for example:

Assistant delegates to Assistant or Supervisor
Supervisor delegates to Supervisor or Manager
Manager delegates to Manager or Director

In general, the delegation must be allowed only when delegating to the same position or higher. Never allowing the delegation goes to lower positions.
