I'm working on my first Jekyll website, and I'm expecting to have a bunch of different things there such as blog posts, a linked list, photo albums, and so on, and have thus prepared a whole bunch of layouts to suit each of them.

So I was wondering if there was a way I could get Jekyll to set permalinks based on the layout, so that posts have their permalink automatically set to `/layout_name/yy/mm/post_name`.

I've been digging around [Jekyll's permalink documentation](http://jekyllrb.com/docs/permalinks/) and various Jekyll tutorials, but to no avail, and now I'm wondering if it's even possible to automate this.

Any help will be greatly appreciated, thanks!
