In the same way you are able to reference a property on a custom table via the many/many relationship custom field, it would be great to be able to reference properties on standard record types via the relationship link.
For example, on a feature, I have a "Releases" custom field. When a feature is moved from one release to the next, we populate the releases custom field with the original release.
In a worksheet, I'd like to pull the "Original release date", or "Original release status" for example. Ideally I could pull something like
min(self.custom.release_history[].release_date)
This has a variety of extensions - because it allows me to access metadata from linked records joined via the custom fields (which isn't possible in reporting today) and not just the name of the record.
