[X4U] Edit iPhone message

[Paul Moortgat]

I regularly fill in our crossword puzzles.
I used to send it now from my iPhone to a number address.
I need to send them the solution followed with my name and address.

The solution is the only thing that will change.
Is there a way to edit an existing message and change that word keeping my address not touched?
It's a pity TextExpander doesn't work in Message.

P.S. I just won a PC which I'll give to my brother.  He just need one.
