[users] CHIRP editing question

Simple editing question:  I can select and edit a row, but I can't select and edit a column.  For example, I want to select the NFM mode in multiple rows and change it to FM.  There doesn't seem to be any way to do it.  If I select multiple rows, it will only change the first entry in the column.  What am I missing?  I would like to see it work more like Excel.
