Custom Mass Action update rows with reference field

Hello,

I am looking for a tutorial that explains how to create a custom Mass Action to update rows using a lookup reference field from another object.  I have been searching but am only able to find a tutorial that specifically uses a Reference lookup field.   (exactly like the out of the box “mass update selected rows” action).

Thanks
