MSS - Team calendar - employee search and or tree structure

Hi,

We have created a custom evaluation path (based on the A/B 290) relationship and custom view in the team calendar. All working fine. The calendar view display the list of employees for whom the administrator is responsible for (based on A/B 290 relationship). The administrator may be responsible for more than one organization unit and therefore the list of employees displayed are in this example more than a 100 employees which make it difficult to scroll down/ up to see the employee in query

Is there any way that the team calendar view can display a tree structure of the organization units (like MSS_TMV_EE - group organizational views) and or search employees within the team calendar?

Any response will be gratefully received.

Regards,

Terence
