I have 2 lookup fields on my form, new repair request form, one lookup field for the customer and one lookup field for equipment. I already have the customer and equipment forms connected with a bi-directional relationship and only the equipment related to the customer show up in the equipment lookup field. I have the equipment lookup field set to "Allow new entries". 

Now to my actual question. Is it possible to auto fill the lookup field when adding a new entry in the equipment form field so it automatically assigns the appropriate customer based on my customer lookup field?
