Ability to create multiple extrude meshes in one command?

Hi all, I am a university student using PrePoMax for my final year FEA research project, in which I am modelling a elastomeric-and-steel-cord conveyor belt (i.e. steel cords held in a rubber casing). I have created the model in FreeCAD and have so far been using Extrude meshes for my simulations. (I also have another post open asking a different question relating to my project)

So far I have been using scaled-down models in my project, and I have been creating the extrude meshes on each cord individually (i.e. each cord part has its own extrude mesh item in the system tree); however, I have now reached the point where I need to rescale my model to full size to continue to make meaningful progress. However, the full scale model has around 140 cord parts. I was wondering if there is a faster/more efficient way to define the model meshes? I have attached a photo below of my small-scale model for reference (note that the cords are extended in this drawing; this is purely for photo display purposes only - in my simulation models the cords and rubber sleeve are the same length).

If you split your wires into volumes with 5-6 faces having 3-4 edges each, import this to PrePoMax and create a compound part, you will be able to mesh them with one Transfinite Mesh object.
