Display order and control for Instance Definitions

D276: As a customer who uses predefined instances, I would like the ability to change the order of the instances so that I can be sure I've define all the proper instances that I need.

when we create a Multi-instance job, we have only 2 or 3 instances.
After several months, we complete this job with news instances.
Unfortunaly, it's impossible to change the display and the priority of multi-instance jobs

I want to manually move the order of instances in job master by buttons (up and down).

for example: today, if I have a multi-instance job with a resource:

First:
My job Instances are:lot=12lot=20lot=10lot=11 If I want change the order, I must delete all of them then create again… Can you create 2 buttons to change the order of lines (for Job and schedule instances) ?
