Multiple Text Entry Quiz, individually scored

Hi, all. I am stumped on this and can't seem to figure out how to achieve what I'm trying to do. I have a quiz slide where the user needs to type a number in 7 different fields, then add them all together to enter the final total (8th field). I want to tell them if they are correct/incorrect, during each step of the way - give feedback - for each of the individual fields, one-by-one. I see that Articulate can only evaluate 'one' per slide.

The only way I have seen, in the forums, for scoring multiple fields on one slide, is the  example here: https://player.vimeo.com/video/145578775  But that scores them as one group, not individually. 

Can this be done? Making 8 question slides for each of the fields seems so clunky. It seems like this is one of those situations where they'll tell me to make a feature request. 

Project attached. Answers on slide 2. They have to look up information and fill in each field on the right, then do the final score at the bottom. Any advice is appreciated. It's been an eternity since I've had to build a complicated quiz slide, and after an hour of searching the forums, I'm at a loss.
