Conditional formatting with more than 15 rules

Hi everyone,

I need some help with conditional formatting. Even though it seems simple at first, I haven't been able to find a solution to this:

attached you will find an example of a regular excel sheet which has in reality about 20-30 columns with different conditional formattings depending on what the column is needed for.

The issue that I have... I want the very first column to be like warning that there is a violation of the rules in any of the rest of the colums (B-S for example)

How do I accomplish it without setting 15-20 rules for every cell in the 1st column??



Thank you so much for your advice!!
