Dashboard - Slicers

Hello!
I am organizing a dashboard to present company's results.

What I want to see is the evolution of customer sales each year and what they represent in relation to total results of the company.

The central sheet is the "Vendas" sheet in which I have associated each document with the day, customer and transaction value.

What happens is that I want to start organizing information and excel does not allow me to use slicers. Someone can help me? Thank you!
