I have a formula for Margin on my Products Details (Price minus Cost). I want this formula field to be added to the pricing subform within the quotes module. However, when I pull up the "Fields of Lookup Module" when I select "Add Field" it is not an available option. Can you please add formulas to the lookup module.

Image below is of the layout under the "Products" module. You can see "Margin" is a formulated field

Below is an image of the layout of my "Quotes" module. You can see under the "Add Field" option of the subform, that "Margin" is missing from the "Fields of Lookup Module". Please allow formula fields to be added.
