As an example, when I add a feature to an epic, I want to automatically update the goal and initiative of the feature to be "the same as" the epic.
Another example: idea categories can't be carried over to features. I might create a custom field in the feature for "category" and I would want an automation rule where the custom field on a feature will be updated to be "the same as" the category on the idea.
Unfortunately without this type of option you would have to create so many rules to accommodate the most common uses cases that automation for us is something I can't see us adopting. We were really excited about cutting down on the huge amount of data entry we ask our PMs to do in Aha and unfortunately automation doesn't offer that for us. I think the use case above could be extend where in a bunch of scenarios instead of picking a "Specific Value" you could select "Same as" and it exponentially expands the value of the automation rules.
