Standard choice

Hello, I am interested in the following software: WooCommerce Product Variations Swatches

I have variable products with several variables. Can I set it so that the first variant is always and automatically selected and the customer can buy immediately?

Currently they have to select a variant first and can then buy, but I would like the standard variant to always have the first variant preselected.

I don’t want to define the default variant manually in Woocommerce because I import my products via a merchandise management system and there I can’t select the default variant but only the order.

I look forward to your answer.
