Modify Mapping on multiple objects

I would like to apply (modify) same mapping on different object, but if I select multiple object I can’t access to Custom texture mapping options.
There is a name property for each, but I do not understand function of it…
My actual method is to Copymaterial from source, then Copymapping from the same source… Is there a way to copy both, or to define the ref Name of the source object to match mapping?

Thank you for your help

Hi Antoine - use MatchMapping for this - I think that is what you want here.
