I don't know how many playlists you have, but the way I did it on either the iPhone or Mac is...
  1. Create a new playlist
  2. Drag an existing playlist (not tunes from the playlist) and drop it onto the new playlist
  3. Repeat the procedure with another playlist.
  4. Continue until all playlists are added.


If the primary objective is to have a playlist that will play every tune your have there is an easier alternative
  • Create a new SMART Playlist using this rule.
  • The advantage here is new tunes will be added automatically with no action required on your part.


Playlist View Options (at least in Big Sur)
  1. Select a playlist
  2. On the menu bar select View As Songs
  3. Then either select View > Options or press ⌘J to bring up the column browser


NOTES:
  1. When adding a playlist that has tunes that duplicate tunes already in the playlist you will be prompted whether or not to add the duplicate tunes.
  2. As most of my playlists are "Smart" I have yet to discover how that will affect the content of the "Master" playlist but I expect it will change dynamically as tunes are added
