Hi Daniel,
Currently, this is not possible by default.
I would recommend trying this brilliant tool to achieve this:- https://wordpress.org/plugins/variation-duplicator-for-woocommerce/
Follow the tutorials on the product page.
Let me know if this solves your problem.
Thank You
Set Multiple Images to Other Variation?
Daniel Mello
Hello! So far, the other gpu-ins work great, but I think there may be an issue between with one and Variation Images Gallery. I want to set a core image, and also another gallery image for that variation, THEN copy that across variations. Possible?
Any help is greatly appreciated. Thank you!
