In the new Reports Pivot, it is possible to add parking lot "releases" but when displayed in conjunction with other releases, the Parking Lot release shows up in the leftmost column.
The request is for the ability to customize the order and have the option to display the parking lot items to the extreme right since they are essentially backlog items that will likely be delivered following the other releases planned releases.
Thank you for the idea. This is possible today by sorting columns in the pivot. The status of this idea was out of date. You can learn more here.
Thanks Matt for adding this in. From a road mapping standpoint, having the parking lot in the extreme right makes it more logical for me.
