Ability to store the settings in the Drupal Configuration as Config Entity

Problem/Motivation

Now the module provides the ability to store the configured settings in the database as content entities - that's good. But in some cases, we want to store some settings as Drupal Configuration instead of content (we can exclude them from syncing using Config Ignore).

To cover this case, would be great to add the ability to choose the storage type for each setting type - content or config. Is it hard to implement?
