Can layers be identically linked/synced?

Is it possible to have identically linked / synchronised layers across a setlist? In such a way that if I were to edit one of these layers they would all be identically updated?

A classic example might be a situation in which you would like to change your default piano sound across the whole setlist. It would be easiest to do this once, rather than locating all the layers that contain this sound and updating each of them separately.

There is the Global Layer, and there are Shared Instruments. If you change a shared Instruments’ sound within the plugin, it will be changed everywhere.

Thank you for your reply, @musicullum. Indeed, Shared Instruments looks to be the right solution for me. I did, however, run into a serious problem, for which I’ve started a new thread (link for anyone else who is looking into this also).
