i attended this years TechED in Berlin and saw the world premiere of Desgin Studio 1.4. During the Live Demo in that session an Adhoc Template was shown in which you were able to search for Queries and select them as a DataSource. Jeroen also mentioned this in his Blog post http://scn.sap.com/community/businessobjects-design-studio/blog/2014/11/14/world-premiere-design-studio-roadmap-design-studio-qa-studio-in-berlin
I was expecting this to be a new feature of the Adhoc Template but it doesn't seem to offer this feature out of the box and i found no mention of it in the User/Admin Guides. Does anybody else have seen this Demo and was able to get this running or knows how you could implement this yourself?
