We have a field on the "Sub Test Execution" task that is called Test Environments, it's a multi-value field, same as labels, here is a picture:

How could I write this in the quick subtasks plugin to use this custom field? I tried many things like:
- cfield:"cf[11424]:DEV"
- cfield:"Test Environments:DEV"
- cfield:"testenvironments:DEV"
But no lucky so far ... thanks in advance for any help!
