remove labels or rows in total column

I would like to remove certain rows in  the total column (here labelled "year to date"). This column is generated in the matrix visual. The totals are fine, but need to change the label. Can that be done in DAX or is there an other way?

Update: What I mean is not change the label of the column, but row or hide some rows within that total column. For instance, I have a row in the total column called  "Actual" but I would like to hide that row.
