I teach science, and there are times when in a quiz, I want the students to have a Lab prompt with a data table, and answer a series of questions about this. 

In the formula style question, you are allowed to give a parameters for randomly generated numbers in questions so that every kid gets a different number.

The feature I am suggesting is the ability to have a formula like prompt in a question stimulus that I can then attach questions to. 

It might look something like the screenshot below, where in the table, the numbers in the table of the stimulus are the `x` and `y` of the attached formula questions.

This would also allow me to make questions much closer to NGSS and the Next Generation Science Assessment.
