specify different post slider icons

Hi guys,

I know that when using the post slider, if there is no preview image designated for a particular post it will default to the standard icon. However, I was wondering if it was possible to specify a particular icon for a particular post.

For instance, under “Recent Bible Notes” on the homepage (www.understandchristianity.com), am I able to use the custom icons we created for each book of the Bible (as seen here: http://www.understandchristianity.com/bible-notes/ ) for the posts that appear in that homepage post slider?

If you need more clarification, please let me know.

Thanks!
Brock
