How can I locate the 'product-template' section to add a pre-order option?

[JustInCase-de]

Hello,

I have one sold out Item in my store and would like to add a pre-order option to that product.

According to the answers I already found, I am supposed to create a new section within the theme code, like this:

product.pre-order.liquid

and then look for the following section:

{% section 'product-template' %}

But, how am I supposed to find this section, when “product.pre-order.liquid” is completely empty (no codes), as I have just created it ? I don’t understand. Or am I supposed to look for that section elsewhere ?

This is my theme copy with the corresponding item: https://4af40ukxmybplqvt-64572260616.shopifypreview.com

Looking forward for somebody to help me out.

Kind regards.

Thank you for your response.

I think you misunderstood my request. I still want the item to say “sold out” but also have an additional button saying “pre-order”.

Kind regards
