Automation rule that adds a new row to a custom table

In my use case we have a custom table on releases to track changes to the release date. I would like to set up an automation rule so that "when the release is updated and the date field changes to anything" then "add a row to the custom table with field 1 = x and field 2 = y, etc".

For this to really work well, we would also need to be able to copy the release date from the release to a field in the new row (idea A-I-9744).

This would be a huge help in tracking our data consistently.
