Thank you svinto for the workaround, and better still, for explaining the reason for the workaround.
I considered adding a file, but thought that it could not be the answer because
1) you need to save the extra file with the original set, and edit it before re-up
or
2) you need some kind of administration for which files need "Hello" and which ones need "Hello again"
It means extra work one way or the other.
My respect for posters keeps growing and growing.
I just had an idea.
If it works I'll explain how on the next round of re-ups.
Yes drolli, changing the date on a file was the idea.
it should work and it does.
