NF Graphic Design on "[Plugin: WooCommerce] Add text under "Calculate Shipping" in Cart"

In the cart totals page of Woo Commerce, I want to add a note ”Free shipping on orders over $75”. To make it more complicated, it needs to show that for regular user groups and “Free shipping on orders over $500” for user group wholesale. Ideally I want this to appear under calculate shipping in the cart totals box.
