goodman/amana techs, question about ctk03

I was just getting frustrated with my ctk03 not working to directly control my humidifier (hum out with 120v on hum in) outputs on my amvc8 furnace. So I went searching for information and it seems that goodman/amana know the ctk03aa unit cannot control humidifiers directly on the furnace, but that an updated version, the ctk03ab, can. (based on a presentation they have on their training site)

Do you know if the thermostat can be upgraded to the ab series?

If not, I think I need to get some kind of interface module to allow the thermostat to control it separately. Any hints?
