Filtering on calculated measure

Hi,

I have a created a report where I have 2 main tables (to simpilify) SALES and COSTS where the main entity for both is "BRAND":

To connect the two I have a created a custom table:

UNIQUE_BRAND = DISTINCT(SALES[BRAND])

Then I have created 2 calculated measures:

MYCOMPANY_SALES = CALCULATE(SUM(SALES[SALES]), SALES[BRAND]="MY COMPANY")

MARKET_SALES = SUM(SALES[SALES])

Because my target is to create a graph like this to compare MY COMPANY SALES vs MARKET SALES:

This is working fine, issues come when I add a filter using the UNIQUE_BRAND[BRAND] I've created because I want to use it to create a subset of the market and compare MYCOMPANY vs One of more BRANDS:

I built the UNIQUE_BRAND table since I want to the same using the COSTS table so I cannot filter directly on one table, how should I build my meausres to avoid that they got filterd correctly?

Thanks in advance for the help!

Thanks
