I think there should be an option to add the releases phases within a parking lot.
|Release time frame|
Thank you for your idea. Release phases are time-based which is why it is not possible to add them to parking lots (which contain no timeline.)
At this time we are unlikely to make changes here. We hope you can understand. In the meantime, please share more details on your use case in the comments. There may be a better solution that we can recommend or a different idea that we can merge this with.
