Setup Rate frequency for plan for 24 Pay periods for one year

Summary:

Hi ,

We have a requirement that the deductions are only taken on the first two checks of every month, 24 payments over the course of one year. How do we setup this frequency for rate for the plan as i do not see the options.

The Annual rate displayed for the plan should be for 24 pay periods, currently it is displaying 26 pay periods as we have set the rate frequency as bi-weekly.

Example:

Employee Annual rate is calculated based on 26 pay periods. But we want to show for 24 pay periods (which is first 2 pay cheques in a month) 

Thanks,

Carine,
