Inserting Matrix columns that do not affect totals

I have a Matrix that presents the data in the following manner:

• The Product Line is an attribute of the product being sold.
• The sale amounts are currently using a measure that I created (I think I did this so it would present $0 if there were no sales instead of blank)

Total Sales = if(ISBLANK(SUM('Sales Order Lines'[Sale Amount])),0, sum('Sales Order Lines'[Sale Amount]))

I need to add a new column into the Matrix that is based on a different attribute (the customer), but that new column cannot inflate the total in the last column in some cases.

For example, a COOKING item was sold to a customer considered INDUSTRIAL. The sale amounts would display in both the COOKING & INDUSTRIAL columns, but not affect the totals (as shown below).

Another caveat to this as that INDUSTRIAL is also a product line on the item so there may be some sales where an INDUSTRIAL item was sold to a customer NOT considered INDUSTRIAL. In that case I would want it affect the totals. For example, a sale was made in Feb for an item that is considered INDUSTRIAL.

I don’t know if anyone can provide me with some advice on how to address this.  I could create a measure for each of the product lines that filters for only what I want to include because these product lines are static, but I was hoping to find a better way.
