Bulk Import from CSV to update across releases so that you don't have to create a CSV for each release.

I’ve attached an example of a CSV file I’ve used to test Aha’s import functionality (comes from a dev system being used). The challenge is that the export gives features across various releases and the current import functionality in Aha requires us to import features per release.

Is it possible to import a CSV file in a way that Aha is able to identify each feature uniquely and update all the other information as required (releases, tags, statuses, etc.) without us having to create separate CSV files for each release. The import will be done to get the features into Aha the first time and thereafter to keep the information in Aha up to date.
