Comparison page layout

Hi tiagopardo ,

I'm not sure if I'm understanding you correctly.
Here is my sample dataset:

I create table(2) and table(3) to create two slicers:

No relationship exists between the three tables:

Use this DAX to create a measure:

Measure = 
IF(
    SELECTEDVALUE('Table'[Company]) = SELECTEDVALUE('Table (2)'[Company]) || SELECTEDVALUE('Table'[Company]) = SELECTEDVALUE('Table (3)'[Company]),
    1,
    0
)

Suppose I want to compare firm a and firm b:

I'm not quite sure why you're talking about the phrase "because the original may only get one company at a time". Because both Filter and Slicer support multi-selection.

Best Regards,
Dino Tao
