Change picture in Rise on labeled graphics page with a photo from the content library

I would absolutely love to have this option to change the interactive graphic in particular from the content library. 

Here is an example of how I want to use a stock image with interactivity: I am teaching multiple perspective taking and want to show different people experiencing the same event but perceiving it very differently. Clicking on the interactive  button above different character's heads would let the learner see what a particular 'character' is thinking.  I certainly don't want to use images of our actual staff !
