and there we are again with “custom graphs” and the nightmare if been used for a bigger bunch of services - in this case Interfaces
We addressed in a different case, that its too complicated, not UX friendly and not working for “bulk-actions” 
@hhpetrov
You want it for accounting (customers) or for devops need?
I guess best way is to open a feature request? (wondering still how other companys doing it - cant imagine creating thousand of graphs for that, or do they all have enough trainees for the job? 
)
