Complex Type Ordering in Enterprise Architect Sparx Systems

I am running into an issue in Enterprise Architect 16.1. I need to be able to out output an xsd from a very complex garden of eden style UML model with the complex types maintaining a strict parsing order, not alphabetical order. How do I do that? The tree which populates the model/diagram always reverts to alphabetical order?

I am new to both Enterprise-Architect (16.1) and generating artifacts directly from a UML model. The data governance procedures I work with require this strict xsd parse ordered complex type ordering come directly from the UML model output, not via a script, XSLT, or any other process in-between the xsd output and the UML model. Has anyone been able to successfully enforce specific complex type ordering in Enterprise Architect 16.1 directly from the UML diagram?

@Geert Bellekens, to be honest, I don't know where the actual setting exists in the UI. I tried to move the element order around (right click on a specific element, then use the move up or move down options) within the Feature box and a prompt box opened up telling me element ordering was set to alphabetical. It asked me if I wanted to turn that option off. I clicked yes, and it let me move the elements around as needed. That single option change resolved all my "garden of Eden" style complex type ordering issues.
