Does vSphere Web Client support third type of Home Screen Shortcut?

Hi.

I am going to migrate vSphere Client from 4.1 to 5.1 version, and in old version, it supports "HomeView.Applications" extension and displays below "Administration" category.

Now I checked  vSphere Web Client Programming guide, it says as following:

---------------------------------------------------------------------------------------------------------------

<categoryUid> string The Home Screen category in which the shortcut extension appears.

Home Screen shortcut extensions must be added to one of the

pre-existing categories on the Home Screen. The following are valid

values for the <categoryUid> property:

• vsphere.core.controlcenter.inventoriesCategory for

Inventories

• vsphere.core.controlcenter.monitoringCategory for

Monitoring

• vsphere.core.controlcenter.administrationCategory for

Administration

-------------------------------------------------------------------------------------------------------------

So could I add other categoryUid?

Thanks a lot
