How to set a default Expense Account in Material Request (Material Transfer)?

Hello expert,

I have a question about expense account in Material Request for Material Transfer.

When I creating Material Request for type Material Transfer, ERPNext set my COGS account as the expense account.

Here are my Material Transfer capture :

and here are the expense account in Material Transfer item detail :

In company list, I set this account as my COGS account :

But when I create manally Material Transfer from Stock Entry, the difference account set as my stock adjustment account :

My question is,
Is there a way to set automatically my stock adjustment account as the expense account in Material Request if the type is Material Transfer?
Or Material Transfer in Material Request in fact always use COGS account as default expense account?

Hope anyone can come up with some ideas.
Best and regards,
