Unfortunately no.  Everything is hardcoded.  Yeah, such a tool would be 
great.  Or, if it would be possible, given a specific database, to know 
every possibilities at once and if the number of possibilities doesn't 
go past 10, we could automatically create select boxes with the 
possibles results.  Else, we leave a blank textbox the user has to 
fill.  Plus, if only 1 possibility is available, no need to do 
anything.  Plus date format doesn't need to be entered either, etc 
etc... ( It's good to dream ).

Do you know if something like that is possible ?

Cheers,

Alexandre
