Different featured image on Home and Post pages

Hi,

I am wondering if there is a way, very preferably without any coding involved (I realize that’s a stretch), to have a different featured image appear on the Home slider for featured articles than the one that appears on the actual Post page itself with the article.

Reason being I am largely reviewing books/comics and the covers are rectangular. These do not fit well in the slider and leave a lot of blank space. As such, I would just like to have a cropped version show up in the slider, and I would like the full image to be on the Post page and show up alongside the summary when browsing tags/categories.

Is there a way to do this? I have zero coding ability so if that’s required then I’m out of luck. Please let me know if I can further describe this issue.
