Where you want to Add the custom line. Please mark that portion.

I have added the custom line items already to the product via liquid.product template but would like these to be displayed when I create the buybutton.

[Zworthkey]

yes, of course

it shows when you will create the buy button 

Thank you

Unfortunately it doesn't? Only the options and variants show that are created on the product page. The extra line items in the product template don't display.
