When creating a master release, one needs to set custom fields for every sub-release manually.
It would be great if one could assign custom fields to master release and they would be automatically applied to all sub-releases.
Thank you for the request. Master releases are meant to be used as containers for phases, milestones and sub-releases to manage a suite of products or releases that have the same release date. At this time, based on current priorities, this structure in mind and historical feedback, we do not have plans for automatic assigning of fields between master releases and sub-releases. We hope you can understand.
