We are relatively new to using Advanced Roadmaps. We are using filters as our issue source for a plan, with the top-level (initiative) filter pulling initiatives from multiple projects. The filter is sorted by project and then rank.
What we want is to see the plan sorted the same way, so that all initiatives from a specific project are displayed together. We can't use the Group By Project option, because that then causes the children of the initiatives to be displayed under their own projects instead of under their initiatives (which are often in different projects than the epics).
There doesn't seem to be an option to respect the issue source's sort order, so how can I make this happen?
