Possible to override browser language setting?

this snippet:
The browser language setting is the primary factor in determining which
language resource is used by the report server for that client connection.
For example, a user who accesses a Japanese report server using a French
version of Internet Explorer will work with French versions of Report
Manager, HTML Viewer, and the report server folder namespace. In addition,
all errors, warnings, and informational messages will be returned in French.

Is it possible to override this for reporting services? I have a user
locale setting in a DB that I would like to use instead of the browser or OS
settings. I can deliver the reports in the proper locale by passing a
parameter, but the settings for the web service still behave according to the
browser settings, as the snippet above describes. In fact, I have a date
format clash that I am not sure quite how to resolve.
Thanks in advance, any help will be very much appreciated.I can solve the date clash by formatting the datetime parameters according
to the browser's setting, but this does not really solve my problem because I
don't want things like selection of report export formats to be in the
browser's language, I want to set the culture information (from a user
profile in a DB).
Thank you again, I am looking forward to your feedback|||regarding my post on whether the locale used for things like the export
options can be set manually rather than pulled from the browser...
I think this will be an easy question to answer for someone on the
development team or simply someone more familiar with microsoft
internationalization than myself.
Thank you very much, in advance.
