Airship allows editors to send pushes to single device prior sending it to the main audience.
This can be achieved after obtaining the Channel ID using the Channel Capturing Tool.
In the message composer under the audience tab click on the Target Specific Users option
Then take the Channel ID you received from the Channel Capturing Tool and past it in the search box
Choose the device id and continue the normal process of sending a push.
**In order to prevent human errors you might turn off the non used platform you pretend to send pushes to.
