How to prorate and apply Tax based on the 'Control Amount' in Tax Tab - AP Invoice Header

Summary:

With only one tax rate defined for the United States, which is also defaulted in the Tax configuration, I'm looking to use the 'Control Amount' function in the 'Tax' Tab on the AP Invoice header to prorate and automatically default that single tax code and create the Tax line. What configuration steps are necessary to make this functionality work?

For example:

AP Invoice Total Amount is $216.50, with "Control Amount" = 16.50

Line#1 100

Line#2 100

The Tax line should be created for the $16.50 so the total Invoice will be $216.50
