Allow quarterly W2 Calculation for Auditing

For Auditing purposes we would like to have the option in MIP to calculate W2's at the end of each quarter so that we can pull a report of the information and then balance the MIP report to our quarterly reporting. We would then delete the W2 Calculation so Employee do not see this information displayed in EWS.
We recently opened a call and were told the W2 Calculation was not possible in MIP Accounting until Q4 because the tax tables were not updated until the end of year. The purpose of our calculation has nothing to do with tax table changes, but is strictly to pull the data for the specific quarter and identify/fix any discrepancies while they are still fresh in our minds vs finding the issue when we are running W2's at the end of year and trying to research/remember what the problem was and how to correct it. We would also use these quarterly calculations to verify W2 boxes for benefits/deductions are setup correctly and pulling the correct and expected data into the boxes.
