Product option value on packingslip/invoice

I've made a new column into the product_option_value table for our OC 2.3.0.2 shop, just like the option value quantity field.

I want to use this field to fill in the location of the option value.
Editing the product and write/read the location value is working now, but I can't get it to work to display this field into the packing slip or invoice template.

Maybe somebody knows a solution for this, I would be thankful!

If you are adding this field on your own, I would rather suggest to look for an extension to accomplish this. If none can be found, please post a request in the Commercial Support section of the forum to get this task done as a custom job.
