Add free text to add to cart module

Hi, I would like to add some text to the hikashop content module, right above or below the add to cart button. The text could for instance be "Ordered on working days, delivered within 1-3 working days."

Secondly, I would like to display the same text somewhere around the add to cart button on the product page. I've tried the option of creating a custom field, but this triggered the content module to show the choose options button instead of the add to cart button.

So how can I put some text here? And maybe a nice add-on would be if I can administrate shipping times to each product, which can be added to the content module or product page?

Thanks in advance!
