With all the QOL changes we have why do I have do search google for different prompts and have to go to WoWhead a non blizzard site to find the achievement and copy the script ingame to get it to pop up.
Can we literally get a functionality for this on PVP panel and not have to do all these steps or get an addon??
You don’t.
Curiously enough they did add this back in Dragonflight but removed it with the Augmentation patch for…I don’t know why, honestly. Maybe collector’s whined about having another +1 that’d forever remain unfilled. 
Or maybe because I think it’s around the time they changed how the script worked to track achis.
/run C_ContentTracking.ToggleTracking(2, ACHIEVEMENTIDHERE, 2)
It’s not perfect but four seconds to look up the achi to grab the ID then slot it into the above script to track whatever achievement.
Ya I found it on wowhead its just obnoxious and stupid if I type “Legend” in achievement search its not the first thing there.
It should be on the PVP panel with glad wins. I downloaded the tracker addon that just expands it on side for you.
This functionality should already exist and doesn’t require some crazy workup on their end.
That’s an addon. 
Yeah, was just gonna say XD
addon is here:

I was lost, not knowing how many rounds were left to conquer Legend.
I downloaded the idTip add-on and then typed the following command into the chat: / execute C_ContentTracking.ToggleTracking(2, 41358, 2).
After that, the achievement appeared on my screen, where missions normally appear.
Yesterday I managed to get the Legend achievement for the first time and I was very happy.
grats on legend
It really is weird that they stopped showing the uncompleted feat in the achievement tab because it was there at a point during dragonflight.
You’d just go into pvp and arena then you’d see glad/legend and could easily click to track wins.
Doesn’t work for me nor the run command Kennie mentioned sad face.
Nvm got it working thanks King
I was just showing how to make use of it in the future so you don’t need the addon to be updated or constantly look for a brand new script
