Matrix - Show columns with no data

I have a matrix where the column header is yyyy-mon from the date dimension table and the values are transaction dates from the fact table.  I would like there to be a column for every yyyy-mon even if there are no transaction dates for that month. 

For example, I would like 2024 Mar to show up but have no values underneath it.  Or, if there is no data for any of the months, I would still like the column header to show for 2024 Feb - 2024- Jun.
