Compensation Rule

We are using Payroll for North America.  We have employees who do not work a full year.  In job data under compensation tab, we need to capture the actual amount they are actually being paid over the period of time they are working and accurately calculate the semi-monthly and annualized salary. 

Is there any way in PeopleSoft to create a rule where it looks at the hire date and expected end date to calculate the number of pay periods the employee is going to work and then compute the correct annual rate and semi-monthly based on comp rate (actual salary employee is receiving)?  Please see example below.
