adding a "quiz question" that is only a small part of a slide

Hi,

I have created a slide, and I am wondering if it is possible to add a "quiz component" to my already completed slide.

I know that I can "insert a graded question slide" but I am looking for something different than that.

Here is my slide:

I want to insert a "quiz box" where the orange rectangle is.  If the user types in "a+b", then I want a layer to come up that says, "correct."

I know how to create triggers/layers.  What I don't understand is:

Is there a way to create a "quiz box" rather than an entire "quiz slide"?

Does my question make sense?
