Open DS -Template via open document language dependent

Hello professionals,

my question:

Is it possible to open a design Studio template via open document in a specific language

Background:

In our BW we send different mails to different users, In this mail we have an open document link which opens an design Studio template from BO-Server. Everything works fine. The Problem is, that the DS-Template is opened in thatanguage escpecially the BW-Content inside) which is maintained as Default language in SU01.

Is there any URL-param as for  BW - Web- Templates to overhand the language and to force DS opened in spec. language?

Thanks for any helpful Input!

Best

Gilbert
