Use a loop to march through your table; untested code below, but it should get you started.

sub dispatch_table {
  my $q = shift;

  my %dispatch = (
    add => {
      confirm => {
        commit  => \&commit_dialog,
        default => \&confirm_dialog,
      },
      default => \&update_dialog,
    },
    remove => {
      confirm => {
        commit  => \&commit_dialog,
        default => \&confirm_dialog,
      },
      default => \&choose_dialog,
    },
    modify => {
      update => {
        confirm => {
          commit  => \&commit_dialog,
          default => \&confirm_dialog,
        },
        default => \&update_dialog,
      },
      default => \&choose_dialog,
    },
    default => \&action_dialog
  );

  for (qw/action confirm commit update/) {
    if (! exists $dispatch{$q->param($_)}) {
      return $dispatch{default};
    } else {
      my $ref = $dispatch{$q->param($_)};
      if (ref $ref eq "CODE") {
        return $ref;
      } elsif (ref $ref eq "HASH") {
        %dispatch = %{$ref};
      } else {
        die "Our dispatch hash is messed up."
      }
    }
  }
  return $dispatch{default};

}
