Removal of "Fixed Amount" option for Tax Calc Override in payroll update.

SOLVED

We are in the process of upgrading from Sage 100c v2017 to v2019.  In testing, we discovered that the option to withhold a fixed amount under taxes has been eliminated.  This is a deal breaker for us.  Our director of finance has indicated that he cannot do his job without this functionality.

Is there a way to get this feature back, or some kind of work-around?
