SecuritySuite - SuiteCRM and CE Teams

Hello, Can we create Multilevel hierarchy through Security Suite. What I need is: A and B Reports to C D and E reports to F C and F Reports to G Now, Records of A and B should be visible to C, but records of C should not be visible to A and B. Records of D and E Should be visible to F, but records of F should not be visible to D and E Records of A, B, C, D, E and F should be visible to G, but records of G should not be visible to A, B, C, D, E and F A simple tree structure hierarchy where lower node can not see records of upper node but upper node can see records of all node present below it in hierarchy. For 2 level, I have created successfully with below steps: 1) Create a role with Owner rights. 2) Assign Owner role to the groups 3) Create a role with Group rights. 4) Assign Group role directly to the C and F Now how to move with next level of hierarchy. I tried to repeat the above steps by keeping A, B, C, D, E, F and G in a new Group with Owner Rights and Group Rights for G. But it made a contradiction, as C and F were also having Group Right. So, records created by A, B, D, E and G started to get visible for C and F also. I am sure I am moving in some wrong direction.... Your help will be appreciated. Thanks..
