Dear Pedro,
Thank you for your query.
This should be perfectly doable.
I see two feasible approaches.
You can either create a family instance for each plate, which is possible but rather convoluted and inefficient, or use a more efficient approach based on DirectShape elements.
It really depends on a number of other circumstances, your workflow, scheduling requirements etc.
If all you care about is just generating the plate shapes, I would suggest using DirectShape elements.
Here is all you need to know on that topic:

I hope this helps.
Please let us know how you end up solving this.
Thank you!
Best regards,
Jeremy
