In some cases you may want to integrate multiple Aha! products with one Pivotal Tracker project. For example, you may have 3 commercial products but one engineering team responsible for development across all three.
This is possible in Aha! under the Integrations in the Settings > Product. For each product's integration, simply point each product at the same project and the features from Aha! will all appear in the same project in Pivotal Tracker.
