range of mac addresses

If you wanted to do mac authentication, is there a way to add a range of mac addresses to the users list. eg: #Normal mac username: 002710de63a4 Cleartext-Password := "002710de63a4" e806882925ce Cleartext-Password := "e806882925ce" #Range of mac addresses: 94ebcd****** Cleartext-Password := "94ebcd******" Dan.
