Customize Sitemap entries grouping

[clementoriol]

Hello. First of all, thank you for your work on this library. It makes my life way easier :)

I was wondering if there's any way to customize how sitemap entries are grouped together ? Is there way to specify that I want 1 sitemap for static pages, 1 for video pages, etc?

I'd love to have more control about how exactly my Sitemap index is generated, and how my entries are separated into different files.
