Is there a way to fill polygons on HERE maps with custom textures or patterns for iOS apps?

Question

I am building an iOS app using HERE maps SDK.

I need to fill the area of my polygon with images/textures/patterns. The NMAMapPolygon.customPattern adds the image as a pattern along the borders of the polygon.

Is there a way where I can fill the entire region of the polygon with the image (in a repetitive manner like a texture)?
