applying a map onto letters coming from the text generator

Hi,
I try to solve the problem of applying One Single Material on different objects, both into Invigorator and Pro Animator.

What I want to achieve is to apply ONE layer map which would appear spread onto the different letters.
No problem with a .ai file, where objects, letters, have been grouped together.
But I'm unable to achieve it with letters coming from the integrated text generator, both in Invigorator and ProAnimator.
In both cases, the layer map (applied at one time on all letters selected) appears on each letter separately. Not spread on the entire group.
In Invigorator, I checked, the letters, created together, belong to the same set.
But how can I tell that I want One map for the whole set ????
And how can I tell it into ProAnimator, where there are no set at all ???
I'm looking for answers into the 2 user guides... nothing.... :-/

Thanks for your help !! :-)
