Hi Thomas.
No. We recently added functionality to move a ticket from one event to another, but it’s not currently possible to reorder tickets within the same event.
You could request this as a new feature (I didn’t find it as an existing request) at our plugins’ UserVoice page.
This allows others who are interested in that feature to easily voice their support. We frequently review suggestions there to find out which ones are popular, then we implement as many of them as we can.
If you post it / find it, feel free to link to it from here in case anyone comes across this forum thread in the future.
