Hourly based payroll for employees with different rate

Its quite astonishing that hourly based payroll with different rates for employees has not yet been introduced in ErpNext. Its very common and i have seen a huge requirement for it too.
Has this been added to the roadmap? can we expect this anytime?

I believe this is not true.

You can create a salary component like “Hourly Wages”, use a formula to calculate this amount.
To use the Base amount (in the salary structure assignment) for the employee as the hourly rate use the following formula.

base * total_working_hours

To manually enter the hourly wage every time you create a salary slip using company currency amount:

base_hour_rate * total_working_hours

Or use the hourly amount not associated with company currency:

hour_rate * total_working_hours

I just learned version 15 hides hours in salary slip. I created a button via client script to add hours (total_working_hours), since I don’t use timesheets.
