Add "External ID" field to the "New Feature" pop-up Merged

My current project works along-side existing tool for QA (HPQC) and Incident Management (Remedy), as a result the features I create in Aha already exist in other tools. What I need is to input the reference # from other tools right at the same time I create the feature in Aha.

This will help to streamline the feature creation task.

Without it, I need to first enter the external ID into the Feature title, then later remove it from the feature title and move it into the external id fied. Double entry for no added value.
