Ability to associate a feature created in JIRA to a Master feature in Aha!

We have Engineers that take the Customer focused epic and break that down into multiple epics (sometimes technical), so we don't want to have them to get out of the tool they work in (JIRA) and switch to Aha!, just to enter the new features for their execution.

We want something in the Jira, maybe a UI (drop down) to allow users to associate the new feature with its correct master feature and have it auto-import back into Aha! as a feature within the chosen Master feature. We’d want the list of options to be owned by Aha! (so it always stays accurate when it is displayed in Jira).
