Hey there Tran,
Thanks for posting about this need. I am happy to report this can absolutely be done!
After enabling the "Split-Ship mode" on the order, you can indicate how many of the item you want to move to the New Shipment that. During that process you can change the number to 1, create the new shipment with that single item, and do so as many times as needed to split your order into individual shipments as needed.
Check out this article about Split Shipping for more information if needed. I hope this helps!
