Are there any plans in the near future to adjust the incident analysis widget to have it work with feature layers from map services? Is there a way to modify the code to make it work with map services?

I think the data used in incident analysis widget should be processed previously to have the capability of network analysis. It is not as simple as find features in a restricted area. So it's hard to use the layers from map service.
