Projector Dynamic Component - How to add new Projector Models

I’ve recently started using a wonderful Dynamic Component from the 3d Warehouse called “Beam+with+Projector” and I’ve been trying to work out how to add my own projector models to the selection of projectors in the Dynamic Component’s list, but I just can’t seem to work out how this is done. Can anyone please offer a noob some pointers towards some tutorials on how to edit the models used within a Dynamic Component like this one?

Thanks in advance, MJJIII.
