Hello,

First of all thanks for choosing our Theme, we are glad to be you in WoodMart WordPress family :-).

There is no such option in the theme to achieve the functionality which you want. You can try some third party plugin for this purpose.

Also you can check the below documentation for the available options for variable products and swatches: https://xtemos.com/docs/woodmart/variable-products-swatches/

Best Regards.
