Thank you so much for the review, much appreciated!
Product addons are not taken into account in our (free) plugin, since they are not part of the core woocommerce functionality and there is no standardized way in which plugins implement this. I’m not sure if this is something that can be implemented, that depends on the details. www.remarpro.com does not allow us to use these forums for commercial services, but if you send an email to [email protected] with a bit more details (addons plugin used, examples of the products on your site) we’ll let you know what’s possible.
