How do I make multiple moving platforms with spikes underneath?

I'd like to make some moving platforms with spikes underneath.

These platforms will move individually when triggered by something (probably a hidden collision event for each one).

I've got a platform sprite, and i've got a spike sprite I can group with it... but how can I duplicate the groups and have independent control over them without making 10x platform sprites and 10x spike sprites?

Thanks for any advice on the matter :)

You can create container for the spike with the platform spike.

On created the platform spike, use for each spike to pin the spike with the platform spike.
