First timer - writing to new car/MPVI 2

I have a couple noob questions. :worship:

I own six credits total.
4 assigned to the Dodge ZF8HP - TCM presumably
2 assigned to the Dodge GPEC2A 2018+ - PCM presumably
Unlocked PCM from HP Tuners - as per instructions I have cleared DTC's
MPVI 2 with latest scanner/editor.

I'm have looked and looked and tried to understand the licensing but I'm still a little confused. And with this license selector confirmation screen using an exclamation point - TWICE ("..cannot be undone!" and "..will not be refunded!") I figure it can't hurt to ask.

Like I said, I have 6 credits and an unlocked PCM with an MPVI 2. I have made a minor modification to the base tune that I would like to write to the vehicle. I would like to make many changes, this being the first. Do I need a credit for each change? Or is the essence of this message that once I write using this MPVI 2, with these particular credits to this particular vehicle they are locked to together?

Bottom line, I want to write to this vehicle MANY times, am I able to do that with this combination?

Once you've licensed the file for the vehicle you can write it to the vehicle an unlimited amount of times.
