Want to see if there is a way ( with sub-tasks or regular task, any issue types) to create tickets and assign them out and make them required to be completed in sequential order. So there is parent ticket and then task 1 must be completed before task 2 can start/be completed, before task 3 can start/be completed and so on...? I know you can require a sub task to be completed before parent can be closed but wondering about the specific task order being organized in the manner explained above.
