Pivot table summary or formula to count field values

Need some help please! I have a source board with the below structure and I need to capture summary values and record them on a separate summary board/item in Monday. This needs to be a separate board/item that dynamically updates whenever data on the source board is modified. I am hoping there is a simple solution with the use of connected boards.

Source Board
Customer 1 TestA
Customer1 TestA
Customer 1 TestB
Customer2 TestA
Customer2 TestB
Customer2 TestB
Customer2 TestB
Customer 3 TestA
Customer3 TestA

Summary Board
Customer1 Test A Count 2
Customer1 TestB Count 1
Customer2 Test A Count 1
Customer2 Test B Count 3
Customer3 TestA Count 2
