Rename column in DAX Studio

I would like to rename the columns of the DAX query that I am executing in DAX Studio. i.e. provide alias via "AS" like in SQL Management Studio.

I am copying the query from the Performance Analyzer in Power BI Desktop, but I would like to change the column names in DAX Studio.

It looks like you cant change the "dimension" column names eg Product, but you can change the measure column names.

Can some please advise?
