Featured Content Image

Is it possible to define the Featured Content image separate from the Featured Image defined for a page? It appears to select the middle portion of the Featured Image of a page, but as I've selected a wide landscape image for the page's Featured Image then the Featured Content image on the home page is showing an un-representative portion of the larger image. As an example, see http://www.amountainhigh.co.uk and the Vanlife featured content image, compared to the Featured Image on the Vanlife page when you click through. It would be ideal if either a) its possible to define the Featured Content image separately from the Featured Image, or b) be able to define/select the portion of the Featured Image that is shown in the Featured Content box. Thanks in advance
