Unity Feedback and Ideas

I have been customizing Unity to the extent I am able to and while I noticed one can filter the various contact groups to show those in a specific province only, this selection does not hold or save once you exit Unity.  It would be very helpful for those law firms that deal strictly with land in a particular province to have the contact lists narrowed down to that specific province only and have the Unity program save this preference. As it stands now, I could not find a way to do this - nor could the Unity tech that helped me in this regard. Thank you.
