Can Modifier in Advanced Pricing be set up to meet various product/customer combination scenarios?

The scenarios as below:

The customer shall get discount for number of products. There are some overlapping among the products and customers, such as:

There are 40 products (Number 1 - 40), 5 customers (A, B, C, D, E):

Case 1: Customer A has the 20% discount for any of 40 products

Case 2: Customer B has the 20% discount for product 1 - 10

Case 3. Customer C has the 20% discount for product 5 - 20

Case 4. Customer D has the 20% discount for products 20 - 30

Case 5. Customer E has the 20% discount for products 25 - 40

I created a Modifier: Type - Discount List, At Modifiers Summary section, Level - Line, Modifier Type - Discount, Pricing Phase - List Line Adjustment, Product Attribute - Product, Product Attribute Value - all the products (repeat 40 times).
