Multiple Language in BW and BO

Hi Team,
Environment is ECC ,SAP BW 7.4 and BI 4.1
Reporting tool : Webi
 
Scenario is that in ECC, text for materials is maintained in both English and local language. The same BI report should be able to show in English or local language, depending on the user.

We are using OLAP Universes based on BEx.we need to display some Fields (Customer ,Material) only in user local language , which is specific to country.All other information will be in English only.
Having another universe /data provider  only to display 2 columns is going to be big task , since we have huge number of reports already developed .
Is there way around for this requirement.
What we are exactly looking is like an attribute to Object ,which will change accordingly with user preference defined at BW.
Please suggest configurations to do in BW and BO.
 
Thanks
