Material Request and BOM Linkage Missing

In Material Request, when we fetch Items using Get Items from BOM, BOM No is not populated in Material Request Items Table. This breaks the linkage between Material Request and BOM. In material_request.js below code is missing the part to populate BOM No

d.item_code = item.item_code;
d.item_name = item.item_name;
d.description = item.description;
d.warehouse = values.warehouse;
d.uom = item.stock_uom;
d.stock_uom = item.stock_uom;
d.conversion_factor = 1;
d.qty = item.qty;
d.project = item.project;

Though it can be resolved with custom client script, complexity arises as other buttons are added in the same code when Material Request is Submitted.
