[Plugin: Google XML Sitemaps] create pages sitemap?

Hello,

I just installed this plugin and so far I really like it. There is one thing I am wanting to do but does not seem possible. I’d like to keep my posts in one sitemap, and create another sitemap of just pages. It would be great if I can create a pages sitemap of a specific parent page and all its child pages. I realize the next major release will allow a blog to split up sitemaps according to month, but I’m hoping it will allow a bit more flexibility than that and split sitemaps up by other options.
