Overlapping Vlan ID in a VCMP scenario

Hi all, we're facing the following problem: we have a VCMP host/guests scenario where 2 different guests, associated to 2 different customers, have to use the same vlan ID; I mean, both customers use the same vlan ID and they can't obviously change it, so I need to understand if it is possible on Viprion side to configure something so that the 2 vlans are seen different despite they use the same tag id towards the external world. Thanks.
