Bulk edit WooCommerce variation prices

WooCommerce comes with a handy discount function. If you select multiple products and use bulk edit, you can set an action price to regular price minus a percentage (example given, give a 25% discount to all selected products). This works fine until you’re using product variations. It’s not updating the price for the variations.

My question is, is there a plugin to bulk update variation action prices? Or is there a way I can just set the variation prices to "inherit" a variable product price? All variations cost the same.
