You can run mass-actions, for example to mass reload units. This is a time-saving and very powerful feature.
Here's an example mass-action, that will reload all units:
Go to the Reports Manager
Create a Units Report
By default, all units will be listed in the report
Select all of the units in the report results
Notice, the red buttons at the top, for mass-actions
Click the Reload App button
Confirm you want to send a reload command to all of the selected units
A reload command will be sent to all selected units
