Using the custom zone for many different items

It orders to make the base more orderly im to ensure charcoal will be explicitly placed near certain areas and planks, logs, and other spare parts material.

However, using the custom zone -/–c/m:logs,planks charcoal wont work

Can people help with how exactly it should be written or if it’s functioning at all?

Thank you.

If its still not working it might be because you pluralized the items.
