It is possible that the result of a pid is given if another pid has x value

Pid B
Show the value of A if B=X else ´´

If you look at the image where it says gear number 1,1 always appears to me, when you start driving it shows the passage of each change 1 2 3 4 5 6.
But when I go back to R it still shows 1.1
What I am trying to do is that if the gear lever is not in D, there it does not show anything, just like the letters of the automatic gears.
Will it be possible?

Here is a picture of the panel.
Everything is functional except tire pressure and oil life. I think it’s because of my odbd2 bluetooth, I bought a new one that is on its way from ebay an OBDLink MX+

sorry my english

I was able to call another pid and fetch its value, but I couldn’t get it to continue if that value is X.
I was also able to call another virtual pid, but the same as in the previous one I couldn’t make it do what I want
