If you can’t normalize (are you sure?).
When you build your query and add each field to the grid, you can then add new names in front of the field names from the table in the format:
New_name: Old_name
You can then use the ‘new_name’ as a variable in your Expressions. Using 1, 2, 3, 4, etc. as the ‘new_names’ for each of the fields you are minimising the string in your expression. Does this explain it?
