Is it possible to add an event to a block that can trap changes to traits?

Hi

This output is nearly perfect.

I have used the block Api to create all the blocks I need. These blocks have traits also. I have only added blocks and nothing else and I am able to drag and drop each block I need to the canvas and it produces the expected result. I am very happy with this.

So...

1. I drag and drop a block on the canvas and then it renders the expected component.
2. I then select the component on the canvas, are able to add and remove classes to it and are able to change the traits and these are updated on the component in the canvas.
3. I would like to trap the changes I make on the traits for the component. Is it possible to add an event to the block directly to trap these changes.

Please note I have only added blocks with traits and have not added any types.
