Bom Quantity question

In my assemblies I have some parts that are "As Required" quantities, they're things like tape and materials that come in sheets and then have to be cut into required shapes, rather than entering manual rows into the BOM, I've created dummy parts that have the appropriate numbers and fields, however, in the BOM the quantity reads 1, I want to read AR but without having to manually edit and fill the field, any ideas or solutions to make this happen?
