Limit on logic for each question

I want to a assign text to a variable based on the answer to a multiple choice question. 

for example, 

If [Answer chosen]=A then replace @variable with “Text for A”

If [Answer chosen]=B then replace @variable with “Text for B”

…. but there are 13 options. 

Typeform only lets me do 7 or 8… 

I understand I can’t easily assign an answer to a variable in any other way?
