Cannot import groups during test taker import.

[tom-diversus]

As the title says, while importing users into Tao, you cannot assign groups to the users. This cannot be done by using any of the combinations used below that I have tried in an attempt to add a user to a group I have called Group 1:

EXAMPLE "CSV":
Year;Class;Student ID;Student password;Name;Gender;Email
0;"['Group 1']";1000;test1;TESTUSER;AH;test@test.com
0;"[Group 1]";1001;test1;TESTUSER1;AH;test@test.com
0;"Group 1";1002;test1;TESTUSER2;AH;test@test.com
0;'Group 1';1003;test1;TESTUSER3;AH;test@test.com
0;Group 1;1004;test1;TESTUSER4;AH;test@test.com
0;"group 1";1005;test1;TESTUSER5;AH;test@test.com
0;'group 1';1006;test1;TESTUSER6;AH;test@test.com
0;group 1;1007;test1;TESTUSER7;AH;test@test.com
0;"group_1";1008;test1;TESTUSER8;AH;test@test.com
0;'group_1';1009;test1;TESTUSER9;AH;test@test.com
0;group_1;1010;test1;TESTUSER10;AH;test@test.com
0;"['Group_1']";1011;test1;TESTUSER11;AH;test@test.com
0;"[Group_1]";1012;test1;TESTUSER12;AH;test@test.com
0;"Group_1";1013;test1;TESTUSER13;AH;test@test.com
0;'Group_1';1014;test1;TESTUSER14;AH;test@test.com
0;Group_1;1015;test1;TESTUSER15;AH;test@test.com

In other words, your documentation just omits the fact that the option to import groups is there but doesn't work?
