Edit join expression

Hi , in the given scenario of both tables having the same columname [ as_of_date ] as shown in image.
Instead of using drop down list, are we able to use edit expression instead. for an example in sql query. tablename1.as_of_date = tablename.as_of_date . is this possible ?

@FaridAvesko yes you could use a join expression for that case, but there wouldn’t be a reason to do it for a just straight foreign key - foreign key join.
