Is it possible to generate RSS feed that includes pages of all languages?

When the Multilingual Mode is enabled, Hugo generate a RSS feed for each subsite.
Is it possible to have a global RSS feed that include all new articles of all languages?

You can use .Site.AllPages in your RSS template, which returns β€œan array of all pages, regardless of their translation.” See here.

Thanks! That is certainly helpful. In addition to .Site.AllPages, we also need to use .IsPage to filter out tag pages, etc.
