Add a URL to a shape object

We’re trying to use/evaluate the diagramming tool using the Decision Tree. We need to be able to have a custom field for a URL on each shape, and then have the shape or area be clickable. I’m struggling with figuring out how to add these to the existing shapes (if possible) or create duplicates of each shape with the additional field and then render it.

Can this be accomplished and if so, I think I need a “dummies” guide on how to do it.

Hello.

You are able to create your own custom shape templates with any needed html-content.
Here is the example:
