Best way to depict choice of two parts?

I have an assembly where I would like to give the assembler the option of using two different thread sealants (one is applied manually and the other is applied by machine.) What would be the the best way to show this on a drawing? The red-lined drawing that production gave me has a slash between the BOM balloons, but I don't think SolidWorks will let me do that. Attached is a picture of the current depiction, without the option of a different sealant.
