Parent warehouse and child warehouse

Hi everyone, i am new using Dolibarr and i have a problem with warehouses.
i am using Dolibarr v18.0.2.
The problem is that when I create a parent warehouse and assign the child warehouses to it, what I want is for the parent warehouse to show me a sum of the stocks of all the child warehouses and a list of the child warehouses.

Hello,

Not possible for now.
May be external modules can help.
