[PENDING] Exporting data to files (which plugins ?)

[eluser]Morty[/eluser]
I can't change the query to display what I actually want because some of my info need to be aggregated.

Example:
idSite | Where | Qty
ALO | C5 | 10
ALO | C6 | 10

I need to save:

idSite | C5 | C6
ALO | 10 | 10

That's of course simplified.
