Role modification in SAP BO Cloud

Hello SAP BO Cloud Experts,

I'm wondering if in my budget report (planning) is it possible to make some role modifications. I need to plan the budget. I created the report and have the dimension 'EMPLOYEE' divided into teams, then the each team contains some members (2 lvl hierarchy). I need to assign the manager the role to modify only his teams budget, he should not be able to modify other team budget, even see it. Is it possible to limit his role to only his team members?

When I looked at role settings there are only roles assigned to concrete dimensions, but not to dimension values.

Thx in advance 4 help!
