Hi Rick,
No - IMHO - I am not able to change the subject using this granularity. That exactly is my problem. But I have workitems for each position and not just one head. The new question is why am I not using the possiblity of multiple items in one notification? The reason is that I don't know exaclty how and that the requirement is just one notification per category.
Greetings and have a good start into the week,
Vanessa
