Addon to auto mark targets upon pull

[Thismymonk-nozdormu]

Hi there! Guardian druid here.
Mostly focusing on Mythics through the LFG tool, I’ve come across lots of encounters where certain mobs needed perma interrupting/focusing.
Having to manually mark those targets so my group knows who to prioritise takes quite the time. Especially in higher key dungeons this can be deadly, ultimately lowering your overall uptime.
I’m aware that this is a minor inconvenience to most people, but as a tank I want my mates’ attention where it’s due, and I convinced myself that other tank players share this feeling, thus the question;

Is there any add-on that lets me prepare markers before entering the dungeon so that, when I pull a specific group of mobs, some of these mobs are marked, and when I pull the next group, that process repeats?
Or is there a different method you people use?

Thanks in advance for any hint

Weak Aura has an automarker for dungeons.

You’d need the addon first, then add this

Thanks alot for the response! I hadn’t been able to find anything like that, so I’m astounded to see this already exists. Anyways, I will try it out and see how well that works!
