Hostname for Access List instead of IP/Scope

For a BR1-Max or future similar model are there any plans or options to use a hostname instead of an IP address or Scope for firewall access lists planned in the future (or we can take advantage of today?). ie. Allow from ‘hostname’ rather than allow from IP Address / Subnet. Maintaining ACL’s over hundreds of our devices is tedious and would much easier if a hostname was an option for the ACL’s.
