That *is* the documented way to do this - the device tag was created &
applied solely for this purpose.

Why would using the device tag be a problem?
There is no problem at all. 
The device tag is good and I know my case is not usual.
I just want to know if there is a way that can make sure every device would be tested.
Think about this case, if there are already many test jobs with different complexity in queue.
If I submit a bunch of test jobs, the situation might be some of devices might run the test job multiple times and some of them might not even get one.
Anyway, my problem solved. I am lucky enough, I submitted 3 test jobs and every hikey with 4k hdmi dongle got one.

Thanks,
Arthur
