[Observium] Alert for summarized sensors value

Hello,

i have a lot alert checks witch can alert for a sensors, and these are working great.

But now i would like to create an alert like this:

I would like to receive an alert if the PDU hostname match PDU-*-1, and BANK1 + BANK2 + BANK 3 value greather than 10. So if the summarized BANKs value is greather than 10.

So my question is Observium support this alert type where the multiple sensor's summarized value is the condition?

Thanks Br Laszlo
