Sort By Column Not Showing in Data Mart

Hello all, 

I'm trying to set up a date table in my data mart and I'm running into the classic issue of months being ordered alphabetically. In Desktop I would go to Column tools > Sort by Column to sort the month name column by the month number column. However, it seems that data mart is missing this option from the ribbon.

I went into Transform data in case the Sort function might have moved there but again, there's no Column tools and I can only sort by ascending or descending.

Does anyone have a work-around for this? I've tried transforming the date column to month because I thought it would format the data to month name while retaining the original date data but it seems to just change the values to text which brings me back to the original issue of being ordered alphabetically.
