Mass user delete in portal?

I have a feeling what I want to do is not possible in the portal. We are converting all of our UME based users to LDAP. I have created the users in LDAP and prepared the import file for portal.

I need to mass delete about 120 users UME accounts in the portal. Is there a way to perform a mass delete? Unfortunately I cannot filter out the search results for the users I need to delete.

Is there some level of functionality in EP like SU10?
