Javascript 使用 Youtube API，我可以在不检索整个播放列表并循环遍历所有视频的情况下查看视频是否在播放列表中吗

我有一系列YouTube视频，我想知道它们是否包含在特定的播放列表中.我有这样的代码:

  var targetPlaylistId = "some_playlist_id";
  var targetPlaylist = YouTube.Playlists.list("snippet", {id: targetPlaylistId});
  var targetPlaylistTitle = targetPlaylist.items[0].snippet.title

  var targetVideos = YouTube.PlaylistItems.list("snippet", {playlistId: targetPlaylistId, maxResults: 50});

  for (var i = 0; i < sourceVideos.length; i++) {
    var sourceVideoId = sourceVideos[i].snippet.resourceId.videoId;
    var sourceVideoTitle = sourceVideos[i].snippet.title
    var isAlreadyAdded = false;

    for (var j = 0; j < targetVideos.items.length; j++) {
      var targetVideoId = targetVideos.items[j].snippet.resourceId.videoId;

      if (sourceVideoId == targetVideoId) {
        isAlreadyAdded = true;
        break;
      }
    }

    if (!isAlreadyAdded) {
      var resource = {
        snippet: {
          playlistId: targetPlaylistId,
          resourceId: {
            kind: "youtube#video",
            videoId: sourceVideoId
          }
       }
      };
      YouTube.PlaylistItems.insert(resource, "snippet");
      Logger.log("Added video " + sourceVideoTitle + " with ID " + sourceVideoId + " to playlist " + targetPlaylistTitle);
    }
  }

这是可行的，但是我必须 for each 源视频循环目标播放列表中的每个视频，如果目标播放列表很长，我不想这样做.

有没有办法问YouTube"视频X已经在播放列表Y中了吗？"
