Currently this is not possible and the feature is still not on our immediate roadmap. However we find your request very reasonable, its priority compared to the upcoming tasks on the Report Server is lower now.
I would like to ask you to submit it on our feedback portal so others can vote for it and increase its priority. How does it sound?
