Payroll Tax Update 25C - Program Funding Configuration for CT, DC, MA, WA

I am wondering what people in the community did to insert new Fed/State tax data rows in order to facilitate using the new Program funding changes.
Manually update? use Excel to CI? Mass Update program? I am in the beginning stages of evaluating how/when we will migrate to PFF for our MA PFML.
We have a lot of Multi State employees and Exempt students to consider when making this change. Thank you in advance.
