in my country, there are so many conventional merchants.
means, they don't know much about internet things.

so here, my business is to collect their items, then i build channel so that i can upload their product to local marketplaces.

however, in your current api create item, there's only one identity for item, which is organization_id.

as i mentioned it before, all my goods are not belong to me.
and i wanna build new feature, that they can upload their own item from my page, then they can do allocation to each of marketplace that they want.

so i need one more identity, like... which goods are belong to which merchant, so they can monitoring their own item, not all of item that belongs to my organization.

with this, i can boost many new merchants, because they do it theirself. no need to wait of my people to do this job.

thanks.
hope u can provide it
