Table to include the selected dimension values only based on another dimension

[a-5]

Hi,

I have the following dimensions in my data model:

Customer	Customer type
Customer1	A
Customer2	B
Customer3	A
Customer4	C
Customer5	B
Customer6	A
Customer7	A
Customer8	C

I want to create a table in my app including customers with customer type A only:

Customer

Customer1

Customer3

Customer6

Customer7

How can I create such a customer list including customer with type A only?

I do not want to show customer type in the table and also I do not want to create a bookmark with customer type filtering the entire sheet (because other customer types are shown in other charts/tables in the same sheet). 

Thank you for your assistance!

aggr(Only({<CustomerType={'A'}>}Customer),Customer)

I would create the dimension in Script.

 IF([Customer Type] = 'A', Customer) AS [A Customers]
