Traditionally, some of our teams had been using 'Bucket Sprints' to manage backlog items that are in the process of being groomed. 'Bucket Sprints' are 'fake sprints' created on the backlog that will never become real sprints (i.e. will never be started) and have been a convenient way for teams to group stories together to facilitate the grooming process.
With our transition to JIRA Align, Bucket Sprints are discouraged as they confuse the tool etc.
My teams are asking what the suggested best practices would be to handle / visualize issues that are to be groomed. One obvious approach could be the use of Labels for this purpose but labels can also be a bit messy.
What are some other best practices for addressing this within team backlogs.
