We are using 5.1.1, I tried to update to 5.2.0M1 a while back and there were too many visual issues which did not work in that version. I see that 5.2.0.M2 is on the download site now, I may install that in my sandbox and see if there is this feature there. I know we were waiting for a few other little items to be resolved. In theory, I should only have to export my old repository from 5.1.1 and import it into 5.2.0.M2 and things will run properly, correct? Thank you!
