ISN Investigators

Question for any ISN Investigators on here. Have been working with ISN for a couple of months now and have done several Personal Source interviews. Questions and inputting into the system is straight forward, no issues for me.
However, I have only had 1 ESI and I struggled with getting it completed and approved. I’m sure it will get easier once I’ve done it a hundred times, but if there is an easier way, I;m all in.
My issue with the ESI is there are at least 3 different places for questions and answers: checklists, guides and ROI.
Does anyone have a template that covers all the questions from the guides/checklist/ROI in a logical, chronological order they would be willing to share with me?

Surely I cannot be the only one do does not want to re-invent the wheel.
Specifically for the DoD/DIA contract.

Thanks in advance,
CW
