Is there any way to make canvas fillin multiple blank questions case sensitive?

[DOVKRUGER]

I just created a question in a canvas quiz using multiple fillin the blank questions.

This is a programming quiz.
The answer we are looking for is :

size(300,200,P3D);

so:

[size]([x], [y], [P3D]);

each variable has the correct answer specified. Unfortunately, it is case insensitive. I swear it didn't used to be, and in many cases I am sure case insensitivity is a plus. But not for coders.

First: IS THERE A WAY TO DO THIS? I saw on the forum that for single fillin the blank, there is now a checkbox.
This is multiple fillin the blank.

Second: Has the behavior changed? I just want to know if my memory is faulty, because I clearly remember it used to be case sensitive.
