Add ability to choose which release to add a feature to when promoting from a requirement

We had several requirements that each needed to be promoted to features. When I promoted, Aha! automatically added the new feature to the release that the requirement had been in. However, I wanted to add it to another release. It would have be nice to be able to choose which release to add it to as part of the promotion process, instead of having to do so after the fact.

However, this may have been a unique case.
