Reply To: Allow user use another coupon over the auto one

[Soft79]

WooCommerce has filters woocommerce_apply_individual_use_coupon and woocommerce_apply_with_individual_use_coupon to allow for exceptions, but this requires a bit of programming. See for example: https://stackoverflow.com/questions/66109603/allow-some-woocommerce-coupons-set-to-individual-use-to-be-applied-together
