But it's not surprising if OP has forgotten and is oblivious to it.
Where in Dutyfinder is the instance you should just be able to queue into, to remind you it's there and make it convenient.
The NPC isn't even clearly marked on the map. (Or at least it wasn't last time I looked in EW.)
Just doing that shouldn't be a big deal. Ought to be possible by next minor patch once the decision is made to do it.
It's probably even quite fun for some people.
Who knows... if you wanted to be really ambitious, you could even add healing checks for Healers. Maybe even mitigation check for tanks.
Adding it for Expert dungeons might be nice to get people in the mindset. Although, I rather fear, is 'auto attack enabled', would suffice.
