Transfer between warehouses from different companies


I need to realize the direct materials transfer between multiple companies’ warehouses in Stock Entry.
In normal case, we have some filters which don’t allow us to select warehouse from other company.
Basically I need that material transfer would allow me to select Default Source Warehouse and Default Target Warehouse from all warehouses of all companies which registered in my ERPNext.

I found the stock/ file, which contains validate_warehouse_company(warehouse, company) function.
I want to comment this function and comment code that calls this function outside, from other classes.
What further steps I need to do for removing these filters?
