MSS Team calendar issue

Hi,

i have an requirement in MSS Team calendar: there is the option "Display" with drop down to have the different views of the team calendar. I know how to customize it and how to add values to drop down list, etc.... BUT my requirment is: the values of the drop down should be dynamic ! Depending on the managers who is logged in, the values should be ALL org.units under the manager. For example: when manager has 3 org.units under him there should be following drop down values:

All employees

Directly Subordinate Employees

Org. Unit 1

Org. Unit 2

Org. Unit 3

Is there any possibility to do this ?
