Can you customize Draw on Image or Drawing Board widget?

Good afternoon!

Is there a way to add things on to this widget?

For example, I need a highlighter option. And I'd like the capability to change the eraser size. I'd also need to be able to add on more drawing boards? Can you assist me with any of this? 

Sorry, but what you see on the widget is fixed. You can't customize the widget function.

Let us know if you have any other questions.
