IDEA : Variable replacement during clone

I recently read Sarah M and Bruces posts about using a task and subtasks as a clone template for repeated tasks.

And it got me thinking that we could offer variable replacement during clone to make it even more powerful.

In Sarahs examples she has Confluence X.X in each issue that she then needs to edit

What if we could replace them automatically

Something like ${version} becomes the value of a "version" variable at clone time.

I would change the clone dialog to allow a row of variable definitions. We could track those variables per person so they dont have to re-enter them over time.

This would make cloning even more powerful and powerful.
