Thoughts on creating separate "manual adjustment" elements to catch up an employee's contribution?

Summary:

Context on the problem: There are times that our HR time needs to catch up a person on their contributions using the elements. Some of the elements(Pre tax deduction, After tax deduction, Employer liabilities) that we have configured grab their deduction in a % based amount. Therefore, reusing the same element and recalculating the % based manually to catch them up can produce human error. Sometimes it may leave the employee without a paycheck since it is deducting too much.

For some of our tax elements, we created a separate batch of balance adjustment tax elements to cover the scenario above. I linked the doc id used. It seemed to have worked out great and smoothly for these tax elements.
