Hello and thanks a lot for getting both products ! I am really glad you like them both There is the ability to have a nested FlowScript within an NC FSM yes. There is a small .unitypackage within "FlowCanvas/Integrations" folder, which includes the Nested FlowScript State script. Once you unpack it, you will be able to add a FlowScript State in an FSM through the usual right click context menu. Is that what you mean? Let me know. Thanks again!
