I want to make the URL field as nofollow

Hello ACF team, Thank you for creating an amazing plugin .

I have an issue, I hope you will resolve the problem. I am creating a directory website with the help of tagdive newspaper wp there and they use your plugin to add the custom fields. I want to make the website URL field nofollow by default when any user registers their business in the directory but In the plugin, There is no option to make the URL field nofollow. As all the links are dofollow by default. I request you please add the option to make it nofollow the URL field. It will be helpful for all the current and future users of your plugin because the newspaper theme makers have added directory features recently.
