   - Kibana module does support raw dict's
   - We added a RawDictLoader as a util, but this will only serve to load rules to dicts, bypassing most of the value of the core repo

 ## Potential Upcoming Enhancements
 
 - Support for customizable folder structure:
-  - There currently is no support for customizing the folder structure which decides how rules are stored on disk when downloaded from kibana (however, this can also be reconciled post download in whatever manner desired).
+  - There currently is not full support for customizing the folder structure which decides how rules are stored on disk.
   - This means that users have to manually move rules to specific organized folders.

+  - This is tracked in: [#3625](https://github.com/elastic/detection-rules/issues/3625)
+  - However, there is support for using an existing folder structure when importing rules from a Kibana export. This is done by using the `--load-rule-loading / -lr` option in the `kibana export-rules` and `import-rules-to-repo` commands. See [#4891](https://github.com/elastic/detection-rules/issues/4891) and its associated PR for more details.
