How to auto separate 2 orders when I submit different 2 warehouse items to check out

[danny_chan1]

I have 2 warehouses that are  A and B.
I still try to find a function to help me.
As follow:
Firstly, I choose 2 warehouse items together and then submit them to check out. 
when submit to check out, the cart can auto split into two orders.
One is an A warehouse order and another B warehouse order.

Is there anyone or any function that can help with this?
Thank you. Still waiting for your help.
