Looks like a macro will be your best option! The macro can affect a Dynamic Select tool where you can use [FieldNumber] or [Name] as the parameter to filter 1-5, 6-10, 11-15, etc.
I am a bit hesitant to try building something because I'm concerned there may be more than meets the eye, so hopefully that gives you some direction!
I also tried with a Batch Macro but with Transpose and Cross Tab tools.
I divided the columns in to Groups based on the Number which can be written or added as a Constant.
Thanks you !!! Very nice solution.
