Personally, I'd think about leaving the Q&As in Notes. I've found that Notes are easier are to work with than shapes. Other hand, shapes can have a Name

You could easily come up with your own structure/convention for the different types of questions and let Excel decode and format

e.g.


Q-TF-Do Cows Eat Grass
A-T

Q-MC-What do cows eat?
A1-Grass
A2-Meat
A3-Apples
A4-Alligators
A-A1

etc.
