Include Prior YTD in matrix

Is there a way to include the prior YTD in a matrix as a single column when looking at the current year pivtoed by month?

I have  a measure using the time inteligence function that calculates the prior YTD and want to show this in the matrix, so something like this

I have a matrix now which shows the breakdown of the team by month and the total, but can't add a piror YTD as a single value at the end.  it wants to att it by month whch I don't need
