I have a custom profile field on my site that is a multiple value text field (5 values max) where users can enter their kids names. I want to add these to the add to cart form as checkbox attributes (so the customer can choose what kids to apply the product to upon purchase) is there any way of doing this? I tried adding it to the line item via use of an entity reference view but it only returns one row as the user entity.

Any ideas of alternative approaches are greatly appreciated, thanks!
