Changing the Default Watermark in a Custom Visual

I am looking to change the default watermark of my custom visual. I am referring to the SVG that is rendered by default when you first select a visual from the visualizations pane, with no data bindings. I tried creating a default SVG within the visual constructor, and it appeared to work within the Power BI online developer visual, but when I packaged it up and added the pbiviz, the default watermark took its place.

Can this default watermark be modified in a custom visual?
