Not admin but I have found an easy solution so hope this helps fix your immediate need without a plugin.
I had similar need – to add text below the button / above wishlist and again, above meta but below wishlist. So depending on how your store is set up – the order is –
1. Cart Button
2. Wishlist
3. Meta
I use all 3 (as in I have wishlist activated) so what I did was simply add this css to the page css itself – so in each product, you literally add the following custom css to suit –
To add custom text directly below the add to cart button
.product-content form.cart::after {
content: "Delivery in 7 days";
}
This is overqualified for a reason. If you just use form.cart::after then it will also show the delivery text next to the button on the footer sticky cart. So if this is ok, do not use the overqualified css – just use form.cart::after
To add custom text directly above the wishlist element
.product-content .yith-wcwl-add-to-wishlist.wishlist-fragment::before {
content: "Delivery in 3 days";
}
To add custom text directly above the meta / below wishlist
.product_meta::before {
content: "Delivery in 3 days";
}
Hope this helps solve your immediate problem without a plugin 🙂
