Import of attribute images for variant swatch

Hi all

Is there ANY solution for importing attribute images? We have hundreds of variant products where every variant/attribute has it’s own texture. We’d like to show it with a variant image swatch plugin. Importing the products and the variants was no problem. Also to import the additional image gallery. But how to import the attribute image automatically?

Seems like WP all import and import suite can’t handle that.

Best regards
