[REQ] Mod for increasing number of priority levels for stockpile

[laughingowl]

Anyone know of a mod (or willing to make one), that would increase the options for setting priority for stockpiles (low,normal,preffered,important,critical)  to add a few more.

Ideally perhaps just changing it to 1-9,  or perhaps simply adding the catagories:
Lowest
Highest

Thanks in advance for taking the time to read.
