From sprint to sprint, my team works on a variety of cards. Right now, it's as common for them to be assigned to releases as it is for them to be unassigned to a release. I want to see all of the cards my teams work on in Portfolio. However, I do not want Portfolio to automatically assign cards that aren't assigned to a release.
I am new to using Portfolio, so I'm hoping there's a way to accomplish what I'm looking for but I just haven't found it yet. If anyone knows of a way to prevent Portfolio from automatically assigning issues to releases, I would love to hear it.
