Answer 1

1) Mark

2) Press Alt+c to open the Column editor

3) Enter the text there

EDIT

As @chapo commented, it now works great with Alt-Shift-Down and then inserts.

Answer 2

Can you select a column using Alt + Shift + Down, enter one unique character, then use Search + Replace so that your text is inserted the way you want?
