LLY Dual tank tune?

How can one tell from looking at the tune file that it is a dual tank set up?

I am brand new to tuning but have done some research and taken an online class. My Suburban is tuned by someone else, but I would like to try my hand at it. I got a stock Kodiak tune from online, and I have the stock tune from my LLY pick up.

Can you tell just by looking at the primary and secondary fuel level sensor tables? If they have values in both tables (non-zero), does that mean its a dual tank set up? Is there any other way to tell? I can't find anything in the files that controls the transfer pump action.

I would like to take the stock tune from my pickup, do a fuel segment swap from a dual tank tune (C&C), and then I will rescale the tables based on filling the tanks myself one gallon at a time.

Thank you!
