How to parse Youtube videos to existing posts on a site with CMS Wordpress?

Question

YouTube

We need a non-standard plugin for uploading videos from playlists and channels.
This one is already on the site.
We need a solution that allows you to specify the address of the playlist, and that each video is inserted into an existing entry. There is one nuance. The site consists of solutions to problems in school subjects, which have their own serial number. You need to parse videos from the specified playlist and insert each video into your post. For example, if the video with the solution of problem No. 25, then it is inserted into the record about the solution of problem No. 25.
