We use Aha! and it would be great to send and receive work with our partners, who have their own separate Aha! account. Ideally, we could create something similar to a work request (https://www.aha.io/support/roadmaps/strategic-roadmaps/collaboration/work-requests) in Aha! and send it to our partner to accept in their Aha! account (and vice versa). This could work similarly to a bi-directional integration like Jira.
also helpful for large organizations who work together but have multiple accounts. We have LOBs using their own, but also need to work together on goals, initiatives and roadmaps.
