Interactivity in Rise Custom Blocks

Hello Articulate:

We are really looking forward to seeing Interactivity in the new Rise Custom Blocks.
Can you advise when we might be seeing this?

It would be great if the interactivity could include being able to click on an image or object to view callouts of text and/or images.

One way to accomplish this would be to add the ability to display Storyline objects in the Custom blocks.
