You would need a boolean filter module for this. The dimensions would be Location-Product list and Product List.
So for selected Location-Product you could see only applicable product. To apply this filter use global selector and set filter from it (instead of Oct 21 - should be Product list of course)
To automatically match the boolean you can identify the products by part of name of the Location-Product list items using formula RIGHT(<LOC_PROD NAME>, 1) and then apply FINDITEM to Product-list-formatted line item. After this you will have to compare ITEM(Product list) = 'Product item in Location-Product list'
The filter CSS property applies graphical effects like blur or color shift to an element. Filters are commonly used to adjust the rendering of images, backgrounds, and borders. Included in the CSS standard are several functions that achieve predefined effects.
