Pathfinders and Markerlight Question

[Vryizen]

I have been out of the hobby for many years now but have only recently been drawn back in, with the new release of 8th edition.
I have been looking into starting a completely new army - I have pretty much landed on Tau Empire but I have still yet to decide fully.

My question regards Markerlights and how they function in the game.

Let's say I have 6 Pathfinders and I want to fire that squad at an enemy unit. Now with each Markerlight hit I get, it adds a cumulative bonus. Now saying that should I roll each dice separately instead of all together - this would allow bonuses to effect the rest of my firing Markerlights. I have an Example down below:

Pathfinder 1: Lands a hit giving re-rolls of 1
Pathfinder 2: rolls a 1 but because I have one hit already he can reroll that dice roll of 1? He then rerolls and bumps the marker counter to 2.

Another Example:
Let's say the Pathfinder unit moved

3 of the six Pathfinders land hits, would that mean that the 4th, 5th and 6th Pathfinders could fire as if they hadn't moved? Due to the fact, a counter of 3 means you down count as moving so you can fire at normal BS?

Thanks for the help and I hope this is in the right place,

kind of knew at this Forum stuff.

Happy Gaming!

Units don't benefit from their own marker hits.

I do believe that all models firing the same weapon at the same target from the same unit count as fire at at same time whether or not you roll them together.
