Hello at all 
I am dealing with a list issue that bothers me for a while. I now reached a point where no workaround seems to do the job anymore.
The problem: How can I set up a list from a “delegate element” with a list in itself? My goal is to show further information in every list item (delegate element) that is not part of the original table but stored in a separate (local) table.
I hope this next example helps you to understand this issue more clearly. Imagine a table of music playlists (stored on google.docs):
Table of playlists
| playlist_id | playlist_name |
|---|---|
| 1 | Name XYZ |
| 2 | Name ABC |
| n | … |
And a table that only counts how often a list is played (stored locally).
Table of Playbacks
| playlist_id | playlist_playbacks |
|---|---|
| 1 | 6 |
| 2 | 3 |
| n | … |
Now, my goal is to have a list in flipabit that contains information from both tables. Like this:
| playlist_id | playlist_name | playlist_playbacks |
|---|---|---|
| 2 | Name ABC | 3 |
According to what I know so far, I cannot use a third table to combine all information needed for the list, because the playback-information is individual for every user and must be tracked separate. On the other hand, all attempts to connect one element of a list with another table have failed. Maybe I didn’t figure out the right action and filter jet but I am actually running out of ideas 
Looking forwards to reading your thoughts on this. If my explanation is unclear, please let me know, so I can clarify.
Have a great day 
Jared
