It would be great to have the possibility to create a single loop transition that would be applicable to all statuses of the workflow without needing to recreate/reuse it on each status.

Example:

Suppose you have a very simple workflow with the classic states and transitions:

   TODO ---> INPROGRESS ----> DONE

  For EACH of the three states, I want to have another Loop Transition with the same name (let's name it "Change number"). Every time the user clicks on it, a simple screen must be shown, with a single number field on it named "Total number of blocks", and the user must update this info. So, I'll have some validators that check if the number was changed and after that, I have also some other post-functions that change other custom fields in this issue, based in this value that was updated by the user. 

This SAME Loop transition, with the same name, the same screen, the same validator, and the same post-functions MUST be implemented for ALL three status of the workflow. You will clearly notice that it takes three times the same efforts to produce it.

What I'm looking for is: I want to create some "special configurable" transition, that is created ONLY ONCE, with its screens, validators, and post-functions, but JIRA is wise enough to understand that this Loop Transition is valid (and available) for ALL the three states TODO, INPROGRESS and DONE.
