We're using BPMN to capture a lot of the early interaction requirements and flows, prior to story creation. (Part of this is driven by our re-platforming, others by the heavy consumption of external API's to drive much of the business behavior.) Several of the BPMN editors out there (including the one we use - Signavio) will export the file into XML. I'd like to be able to then import that XML and create initiatives, stories and releases, then begin cranking the further story breakdowns from there.
It's currently possible to Import records into Aha! via CSV. You can import features, initiatives, releases, ideas, idea portal users, products and users. Please see this support note for more details: https://www.aha.io/support/roadmaps/strategic-roadmaps/settings/import-data-from-csv-file
There are many XML to CSV converters available which can allow you to easily import records into Aha!
Based on the existing functionality available, community feedback and current priorities, we are unlikely to make updates in this specific area. We hope you can understand.
