Hi Tunettnt,
Not yet, but soon! I am sure there is a way to do it the hard way, but we actually start work on this feature next week for our summer release, code named "Minerva". If all goes according to plan, we should have a cookbook version (read: you're going to need to bake it together yourself, but we'll provide the main ingredients and a recipe) to try out our initial Availability Report within the next two weeks.
Please check out the Product Roadmap Forum, and the Product Roadmap section of the wiki for further details. And if you want to participate in the build process by testing out the pre-integrated reports, respond to the Product Roadmap Forum. We're eager to get the community involved in our development!
Cheers,
-Stacey
