You can do this in a couple of ways..
1) create an encapsulated flow subroutine note and save it in your scripts then You can simply plug in the inputs to carry out task there are tutorials of Using flow subroutine in Stingray learning series of 'SERVO' and in help docs to.. You simply copy all nodes and paste them in external flow editor and plant the input and output switches to make it self-sustainable flow node..
2) The second option you can do is utilizing the Entity systems. If what you are trying to do is part of a system your designing and want it to work efficiently regardless of what it is. You can create and entity for this you can create a special unit or object for it mesh, lights etc in dcc tool and bring in to create an entity . you can control entity by assigning it several tags and property inputs, data, unit, flow, script , transforms, shading environment and other stuff. you can create a data type variables for entity to receive inputs and consolidate the entire within the entity's flow script, so no matter where you might need to reproduce the system, it only requires one time effort and you can effectively and independently use it to create several subsystems for driving your App or Game functionality.
For Example. 'You create a system where a person opens a door and when he enters. The lights near door turn on, and a ceiling fan in that room turns on. Now to instead of replicating and re-implementing flow nodes for all the rooms and Doors. you can just create an entity system in which's flow script you take the input of door unit, its animation and sound events, some inputs of triggers of room, and lights and 2-3 data holding entity properties and named respectively for the desired task, and so you can create entire logic within the entity's flow and only receiving the required inputs for the level or locality. And then you can simply replicate it where you want once it starts working as expected regardless of what u have in the surrounding. You just create an independent subsystem, which you duplicate over,
