Hello - yes, it is possible to recreate the values shown in your screensnip.  It would be best if you have a separate date table that is related to your data table.  Then you would have the separate measures that reference the dates in the date table.  Below are sample scripts for measures along with the url for the associated DAX pattern, which includes detailed explanations and scripts for a date table that you can just copy and paste into your project.  For the scripts below, just replace the table and column references with the applicable table and column names for your project.  For each measure, you can change the number of months to offset from current, which is shown as -1 (for prior month) in the example. 

Add a column to your table 'Year Month Number' to reference in your .  This will be in the format of yyyyMM and will be for the date of the current row (not the date for any previous period).
