I'm sure many other people have said it, and you have highlighted it as a drawback in the release statement already. However, i just wanted to say that without the ability to export the report based on user interaction (drilling / slicer options etc) our users cannot really use it. We generally have a company level report, which users then drill / filter to get to their departments data, and this is what they want to export.
I am thrilled that the capability to export into PowerPoint has become an option, however it isn't as valuable as it would be if the slicers applied to the reports would influence what is exported.
The current set up of the reports requires the user to isolate the group (and there are hundreds of options) to view the data and when it's exported for the entire organization, the end user isn't able to view their specific groups.
I think you just added limitation of 15 pages in this exporting feature, so could you please allow us/users to choose which pages will be exported instead of ask to re-publish report with less than 15 pages and export?
