ArcGIS Online polygon fill symbols

Question

Can you currently symbolize polygons in ArcGIS Online with anything besides a solid fill with or without outline?  If not, when is ArcGIS Online going to pull in more symbolizations for polygons?  I have a polygon that I would like to symbolize with a 50%transparent line fill so that you can see that it is part of a larger polygon underneath.
