Free Gift on checkout page with discount code

[CoolJ]

Hello all!

Has anyone tried working with the free gift line scripts on the checkout page with the discount code? I'm trying to add the gift item(s) to the cart whenever users insert a specific discount code but I noticed from the shopify documentation line item script, it only works if the free gift item is in the cart as well.. can i insert the discount code and the free gift will appear as well on
