My IT dep is servicing a bunch of client all over the city (more than 20 coffeshops)

I have only 2 it specialists and no contact center!

I need to create a rule for auto assignment of the specialist with a criteria called "traffic light"

The ITIL idea: Red (with High Urgency) is assign first to first (load balancing) technician.

Then assign Yellow or Green, Need SDP understand that 

RED = Yellow + 2 Green or 3 Geen or 2 Yellow

Yellow = 2 Green

Green = Green

So every request must have it's own value, so SDP can decide (load balancing):

this tech_1 is working with RED

when new request arrives it's going to tech_2

when new request arrives (yellow or green) it's going to tech_2

and so on..

can we make such a rule?
