JQL for status transitioned by someone OTHER than user?

[Louise Baker]

I have this JQL:
status changed to Available by membersof("product management")

This works great, BUT I want the opposite:

status changed to Available NOT by membersof("product management")

NOT by is not a thing.

Is there a JQL to accomplish this task?

Hello @Louise Baker 

Try this out

status changed to Available AND NOT status changed BY membersof("product management")

Thanks,

Tim
