Hi,
Thanks for your suggestion.
At the moment, EasyStore does not support adding a dedicated custom field on the single product page specifically for inserting module shortcodes. Product layouts follow a predefined structure, which limits the ability to inject custom modules per product without customization.
This is a useful idea for increasing flexibility, I will add it as a feature request. That way it can be reviewed by the product management team and considered for future updates. Any changes or additions will be communicated through official release notes.
Thanks again for sharing your feedback.
-Regards.
