Avoid duplicate items lines in material request

I receive multiple sales orders with hundreds of items. When I create a material request from multiple sales orders by delivery day, many items are repeated in the request, but I am only interested in having only one line per item and see the total requirement of that item. How do I fix that?

In selling settings there’s checkbox for Allow Item to be added multiple times in a transaction

Not sure if this is applicable in material request but I think it should as Item Table is shared with different modules.
