Product sorting

Hello. I’m using the Listing Manager plugin to create a physician directory on a site I’m building. The only issue I’m running into is sorting alphabetically. The problem is that since these are doctors, they all medical certifications after their names, like ‘Joe M Smith, MD’. What’s happening is that it’s viewing ‘MD’ as the factor for the sort, so entries are not able to be sorted by last name. Is there any snippet of code that could be added to my functions.php file to ignore ‘, MD’ and sort by ‘Smith’ instead? Probably grasping at straws here, but thought I’d try. Thanks!
