Increase Autofilter Field By 1 Across The Project

I'm trying to modify a worksheet and I'm having mental block. Basically I have the A:N columns full of data, and about 40 helper columns after that. All the helper columns being referenced by many macros.

I now have to add one more data column after the N column, so the helper columns will be cut and pasted one cell to the right.

The question is, how do I efficiently modify the code that looks at the helper columns to take into account the "1 field to the right" movement of the helper columns? Here is an example of the code

[Code] .....

There are tens of references across the project for every helper column so doing it manually is impossible.
