Flexible content pages are a more advanced pattern of generic content pages as it allows for ad-hoc content elements to be dropped in.
Due to this there is not a strict pattern that needs will be matched when adding content as additional content can be added.
This means that during import workflow we cannot necessarily rely on previously mapped template structure by AI as this page might have some additional
content that was not on the mapped one.
Due to this whenever dealing with flexible content pages they need to ask whether to use existing mapping or do a clean one.
At the same time we want to allow bulk processing for items like blog articles.

The flexible content elements are retrieved from content library (api/search/elements) and can be used to add additional content structure to page.
