Is this poossible with multisite manager

Issue Summary

I have a drupal multisite installation in which all multisites are sub-domains except for the main site. All subdomains share the same modules, theme & blocks. All sub-domains share the same database with different prefix. The user related tables are shared across all sub-domains. I also have vhosts setup so I don't have to create symlinks or anything when I create a new sub-domain. I would like to give users the ability to create a sub-domain and each sub-domain would use the same modules as previous sub-domains. The only thing the user would input is the name of the sub-domain ( xyz.mysite.com ) and the same name should be used as a prefix in the database (xyz_mydb_table). Can this be done with multisite manager ?
