I have created an advanced roadmap with two projects using the same hierarchy, where i create a issue type called Goal that above epic level. In this case, under the advanced roadmap view, I'm trying to put an epic which belongs to project 1, to a Goal issue that belongs to project 2. However, jira doesn't allow me to do so and shows red while I'm trying to drag it to the desired place. I want to keep those epics' project field value, but only change the display in the view of advanced roadmap. Thanks a lot!
