@sncarlos Unfortunately, it is not possible to allocate dynamic elements within the product feed creator section. As a workaround, you can utilize Django blocks for email templates, as described in this resource: https://www.klaviyo.com/blog/solution-recipe-4-extending-klaviyos-product-block-functionality
You can create a comprehensive product feed beforehand and then use a Django block with a for loop to iterate through the products, similar to the example below:
{% with product_feed=feeds.ExampleProductFeed %}
<table>
<tbody>
<tr>{% for item in product_feed %}
<td>{% catalog item.item_id %}
<table>
<tbody>
<tr>
<th>{{ catalog_item.title }}</th>
</tr>
</tbody>
</table>
{% endcatalog %}</td>
{% endfor %}</tr>
</tbody>
</table>
{% endwith %}
include an if statement within the Django template to check whether the catalog item's ID matches any value within the custom property array of the profile:
{% if catalog_item.id in person.products %}
Hope this helps, let me know if you have further questions.
