Is there a way to add actor.firstSeen to the graph in the same way as the NPC deaths are shown?

I would like to create a pin that adds a line to the graph at the timestamp for actor.firstSeen for actors in the expression.

Example for expression Il’Gynoth add spawns:
actor IN ( ‘Corruptor Tentacle’, ‘Deathglare Tentacle’, ‘Dominator Tentacle’, ‘Nightmare Horror’ )

And then I want to see on the graph when each instance of the filtered adds spawn with the help of the actor.firstSeen, since the adds are not actually summoned by the boss - they just appear.

Example:

Thank you so much! This was exactly what I was looking for.
