Hello Quique,
I had a look at the tool.
Because of the spanish language, it was a bit difficult for me
to understand.
It seems, the working of these tools is complete different
to that, what i'm doing :
I don't create a new source.
I want to add values, possible only to find out with a preview.
The reason for my questions is,
i don't want to spend time in things, somebody else created already.
Maybe there are still other tools ?
Thank you very much
Uwe
