Creating shapes/background for widgets natively within Niagara

Hi All, I have attached a screenshot of a small widget I'm currently using on one of my BMS projects. It's a .png file made in illustrator that I'm placing it onto a .px to create different kinds of display widgets. Is there a way of creating the same shape/s natively within Niagara, without having to create an image in Adobe Illustrator first and then bring it in? I'm hoping that if it is made natively, I would be able resize and recolour it within Niagara far quicker then if I went back and remade the image.
