Automatically pre-fill parent for conformance rules

## Background
When I am filling in conformance rules and have a structure of `strings.randoms.long_string` and I want to do for example an `UpperCaseConformanceRule` on the `long_string`. I would like if the output column would be pre-filled with the `strings.randoms.` as the parent that needs to be the same.

## Feature
Pre-fill the output column of conformance rules with the parent name.
