[otrs] Centralized admin area

Hey there guys! Please help me with some information about OTRS. We have a lot of software products we have to organize support for. Users of each product should not know about existence of other projects. But we want a cetralized admin interface to control and answer tickets on ALL the projects. Is it possible with OTRS? Can we organize submitting tickets from different product sites to one centralized system and to be able to personally response to each group within this admin area? Thank you!
