A 'Low Priority' on balancers

I couldnt see a post for this, hope im not repeating a suggestion. We currently have Normal and High priority on conveyor balancers, could we also have a low? As an example, i have an assmenly creating mechanical parts which goes onto a flat conveyor belt and then into a flat balancer which split accordingly - going on high priority to the maintenance depot and normal priority to create lab equipment and vehicle parts. Would be nice to have a low priority going to a storage so things will go into production items before going into storage.
Just a thought :-)
love the game and thanks for the work you have done so far!

Just add that storage right after making them, then leting it output to balancer. This way you can setup alerts (like when you are too low on mech. parts), and you can also use sliders to not output onto belts if you have not enough in storage.
Alternatively place that storage after priority output and use it as a buffer for maintenance, so you will get some time before maintenance run out.

i sometimes need more then 1 or 2 rules in my balancers. So maybe its even better then instead of high/normal/low, Just make it an adjustable number 1-8 for total control.
