Adding custom columns to SuperDOM NT8

As in the word's of Pink Floyd..."is there anybody out there?"

I want to add some custom columns to NT8 SuperDOM but I am woefully ignorant of NinjaScript. I have looked at the code for the "Volume" columns of the DOM but to be honest I don't know what I'm looking at. Tried to look at where the "line" for the volume at price is ,just to try to get a handle on what the new code would look like. Reached out to NT but their response was only that..

"Thank you for the inquiry.
Each column would be individual or would not be able to necessarily share data with the next. To accomplish a rolling concept, you would likely need to copy the logic from the last column into the next column and then expand off of that. I would not have any examples of a custom column, but you can review all of the standard columns and their code..."

Is their anyone who would like the challenge or is it too big of a mess?
Thanks in advance
PS
attached the NT7 I was using and the way NT8 looks
