Technical [Grid Addon] Show Ebon Gargoyle as pet frame (and how to power infusion it?)

[brick12345]

Hello, I'm struggling with Ebon Gargoyle since in the default UI it doesn't appear, and not even while using Grid. I remember it was showing as an additional dk pet under the ghoul but now it doesn't work anymore (or maybe I have a fauly memory).
The fact is I play without friendly nameplates so It's really hard to check Gargoyle health without targeting it, and I play Healer so I need to heal it if needed (I have keybinds to target party1 and party2 pets but they don't work with Gargoyle, maybe I have to press the bind two times to rotate the pets I don't know I actually have no time to do these tests at the moment, or anyway an additional keybind to target it would be hard since I used almost every key, with modifier, don't even know if i have a free keybind available)
How can I resolve this?
Also: why can't I Power Infusion it? On icecrown it's like 1 year or more it's bugged and it won't let me cast PI on it, meanwhile on blackrock and other servers where I play I can do it with no problem, and it's working as intended, so the bug is only on Icecrown.
Thanks any help is appreciated.
