Payroll component

I have five employees and the basic salary and other allowances of all the employees are different. Now my question is do I have to create five different " Basic Pay" components or is there any formula that can be applied to the " Basic Pay" component and fetch different Basic Pay for each employee?
Please anyone

Thank You

I was just describing a proposal related to this on github:

At the moment, there is no simple way to have multiple variable components in a salary structure assignment.

Yes, it should be like that and there must be variability in salary components where a single salary component can be applied to different employees with different salaries. In My case, I have to create 5 different Basic salary components.
