With custom tables being the way to augment the existing Aha! data model it'd be extremely valuable to have the ability comments to capture point in time information. Specifically, would want to use this for keeping notes on customers or risks.
Thanks for the idea!
Currently, you can add a custom field of type Note to your custom table. This will give you the ability to add any additional data, such as customer data or risks as you mentioned, for each row in your custom table.
