    For anyone with the same issue.

     

    I ended up putting an IF statement into a custom column on the table which checks to see if my reference column has a value, if so it is populated with the corresponding date in that row, if not it is populated with null. After that I used a MAX() function in a measure to get the latest available date from my new column and used that measure in a visual level filter.

    Thanks
