How to display nothing instead of "(empty)" in Pivot table?

I have a pivot table that takes a sheet with a lot of expense details, to summarise in a table “Expense Date”, “value” “Description”.

To do this I put the 3 columns as “row fields” in the pivot table (and Data as Column Fields).

However, expenses without description will display “(empty)” in that cell. How can I make it show nothing instead of the string “(empty)”?

I have the same question and I would be grateful for an answer. If it’s not possible, how can I add it to a wishlist for Calc?
