Request to end date salary of an employee when he/she is active while adding new salary row

Summary:One of our stakeholders would like to end date salary of an employee when he/she is active, Few employees are working on temporary basis for a specific time period so user would like to add end date on the same page when creating a new salary along with start date. This will help HR's to keep a track of salary of those employees in case if HR's forget to end date/on if HR's are on leave.

This is requested by HRs as it's possible for them not to miss-out end-dating the salary row, this is especially for the case of temporary assignments- contractors.
