That might work great if you have a few articles to deal with, but if you have a large site with thousands of articles, that get frequently updated this is NOT a very elegant solution.
The auto text generation for com_content basend on the PageBuilder content was a fantastic feature and i cannot understand why it was not migrated to the latest version of pagebuilder - Then again, the entire Article Integration is still very unsatisfying (See: https://www.joomshaper.com/forum/question/27231)
Would be great if this is added to to feature list and implemented soon - It is a major blocker why we can not update a lot of our sites to J4 or 5....
