How to dynamically calculate row total?

[JackFrench11]

I organized my data in power query and used power pivot to create a pivot table off that data model. I have the years 2019-2023 as columns in this current dataset. However, sometimes when I refresh, a 2024 column will be added. How do I create a new measure column that will take the sum of columns 2019:2023 as well as 2019:2024 without me having to manually edit the formula to include the new column?

Additionally, I have metrics that I will be conditionally formatting this table on. For example, I will want all values less than 100,000 filled green. How do I make this dynamic so that it works with the occasional inclusion of another column (2024)? I've tried but when I select 2019:2023 as my value range, it hard codes the formula and does not apply to the new column.

It seems you did pivot the data inside PQ. And then you did another pivot on top of that which is total ...

The query labeled "3 - Pivot" was just me pivoting the rows into columns so that it displays the year as columns instead of rows.

create an explicit measure instead of an implicit measure (calculated column)
