Can't link featured image to post in Hueman

Hi All,
I cant get my featured images on my home page to link to my posts. I have added the post URL to the image before uploading it as a featured image but no luck.

Do I have to put additional code in for this to work or am I missing something obvious. It seems strange that you cant do it through the image at the upload stage.

Any suggestions would be welcome

Cheers
