Info-object labeling in BEx

Client requirement is to show variable description for an info-object depending on a user login.

e.g. a Infoobject (Characteristic) Name is 'Level1' with a description as 'Level1'. If a user in Canada logs in and see a BEx report he should be able to see the description for infoobject Level1 as 'Cost center'. A user in US may wish to see the description for the same infoobject as 'Expense center' etc. etc.

Is it possible to do so ? If yes, please let me know how to do this. Where to maintain these different descriptions for the infoobject etc. ASAP. Thanks.

Pease do not get confused with language dependant texts.
