Mass Delete Routing/BOM Header

Dear All,

There should be a feature to mass delete routings including routing headers, I know we can delete routing positions by using routing batch changes however if I don't need routings for an item there should be a feature to delete all routing data which does not have routing details.

Similarly, there should be a feature to mass delete BOM as well, currently, we can mass delete only BOM material positions but there is no way to delete the BOM header without using a script. If anyone has the script to mass delete routing/BOM header please share it.
