Hello,
I was just wondering if there is a plan to extend ArcGIS Urban capabilities to handle multiple inputs for 3D Base Layers?

For instance, if there are multiple sources of existing buildings (for your city), it would be fantastic to have the capability to have multiple inputs. Thus far I can't determine a non time exhausting exercise to merge multiple existing Scene Layers (maybe there is a workflow I am not thinking of/missing)?
Any comments would be appreciated and helpful!
Thank you!
