Multiple text rotation question

[Grafix Smelter]

Is it possible to rotate, multiple individual characters about their own axis?

The only way I know at the moment is to individually select them, insert a 9 before the 0 and enter return.
In the attached screen-shot I have done 14 and 13, but I would like to select 12, 11, 10 etc. and rotate them all about their centre without them changing from a column to a row.

Thanks in anticipation.
