Woocommerce bulk varition generation and editing

I have multiple woo commerce stores on WordPress, lately I am facing a few challenges.

1. My Products has multiple variation i.e gender, color, size
2. Each color or size has different price, image and product gallery

If I add these products by default woo commerce variation generator it takes a lot upload image 1 by 1 etc.

I tried this WPC Variation Bulk Editor for WooCommerce Plugin it was very helpful, but it doesn’t support block editors, it means I can’t add product gallery for bulk variations.
