Hello, 
I just started working with hardware, firmware and lava. You have a big documentation, but for me it's sometimes difficult to find something. 
I wanted to submit a job on just one device like my "bbb-03" and not on every beaglebone-black. Is there a device-tag to choose a device like "device_type: "? My next question is if there is also a worker tag for a job submit? For example I just want to run all "beaglebone-black" on my "worker2". 
Is there also a list of all job submissions tags with examples? I just found the one for the "actions" part. 
I'm sorry for disturbing and maybe the stupid question. But thank you for your answer in advance. 

I wish you a nice day
