Lose task sorting when save new action manual - number ordering for priority

when i manually sort to sequence tasks and then save a new task Wieldy loses the sort order.  So because I often add new tasks I cannot sort them by individual priority because repeating the sort wastes too much time.

It would be good if a number could be assigned to prioritise.  Two types of indicators for sorting a large number of tasks.  a number range = say 1-5 and then once there is a rough sort you could go in and do an individual sort.  So task "answer letter from John" would first be given a 1-5 ranking and later it could be given a priority number - e.g. 2.  

Also automatic adjustment of task priority number.  If numbered priorities are set and a new task arises that should be priority 3 - all tasks below 3 would automatically be assigned one number lower priority.
