Any PT4 wizards who can point me in the right direction on this one?

I'm looking to build a Reg/Fish badge in the HUD.

First we define two categories:

Reg:
- VPIP between so and so
- PFR between so and so
- VPIP - PFR gap between so and so
- Preflop limping between 0 and so
- plus various other criteria that can be set
- So and so many hands

Fish:
- So and so many hands, and
- Not falling into Reg category

Then we describe what we want, a stat behaving like a badge:

• When a player has less than so and so many hands, no label (invisible or "N/A")
• When a player reaches so and so many hands, player is either labelled "Reg" (in red) or "Fish" (in green)

To get this we need to do some custom stat work with Filter Expressions and make it behave in the desired way in the HUD. Advice from anyone who has done similar things in PT4 would be much appreciated.
