How To Edit Supported Cultures In a Silverlight Project

Is there any way to edit list of cultures supported by a SL project in Visual Studio 2008 using GUI?

Currently I'm doing this by changing content of <开发者_如何学Go;SupportedCultures> node in the .cproj file manually. For example:

<SupportedCultures>
en, de, es, fr, ja, zh-CN
</SupportedCultures>

Thank you.

No. I continue to do this in Visual Studio 2010, too. It isn't much of a bother, though.
