I just wanted to be sure that it is not possible to do that. Case is that 
customers wants to see directly Tier-1 (they think that they are so big 
that talking with Tier-2 discredits them). Of course I'm happy if it is 
not possible and I can say to sales that they should accept us or just 
look for another provider (not easy for them) :-)
