Needs to be easier to reuse transitions in a workflow

If I create a fairly complex custom workflow, many different steps along the way may have a similar transition. For example, there may be several different points along the workflow where you can "Close Issue" or "Reopen Issue".

In the default JIRA workflow, there are two places where you can "Reopen Issue" and they magically share the ID 3. If you copy this workflow, and then make a change to "Reopen Issue" (add a validation or something), it will appear in both places. But if you make a new step, and give it a new transition "Reopen Issue", this is separate from the other ones (it will have a new ID). Sometimes this is what you want, but usually it is not; if I impose a new restriction on "Reopen Issue" that says only a person in a certain role can do it, I want that to apply to everyone.

I figured out how to do this by exporting the XML, hacking it, and reimporting it, but this defeats the purpose of a WYSIWYG editor. We really need one or both of the following:

1. When creating a new transition, you should be able to choose if it is really new, or just shared with an existing one.
2. It needs to be easier to copy conditions, validators, and post functions from one transition to another.
