Loop 2 attributes at once

Prentice

Hello,

I've got a question again and you seem to be amazing at answering them. 

I'm trying to use a loop where I want to filter for 2 things at once inside the loop. I have a dataset with multiple attributes where I have a series of steps that need to be executed for two attributes each with their own series of steps. These need to be executed twice. 

First iteration Loop attribute 1&2, second iteration loop attribute 3&4. Is this possible or do I need to use two separate loops for this? 

I've tried using a macro in the loop function, I made two separate macros with the same name as value 1 and the other 2, but this does not work. 
I also tried using two separate loops but the output is not what I want it to be. Now I need to link one attribute from one loop to one attribute of the other loop. 

If anybody knows how one of these can be accomplished I would really appreciate it.

Thanks

If your columns are named in a good way, like I am showing here. You can definitely run with a single loop.

Honestly I cheated here to only keep one single loop by renaming the columns: every column falling into either bucket .*Failure, .*Inspection makes it easier to search for the columns and merge.
