Song that is used multiple times in playlist shows only once after sync

[I tried search before posting, but couldn’t find a similar post]

To visually enhance the playlist in Rekordbox I ‘separate’ groups of songs in my playlist. I use a dummy MP3 (just few seconds long) named “-----” as visual separator to help me remember the groups of songs that I know how to mix well. As such, that ‘divider song’ appears several times in the playlist

After syncing Rekordbox to Lexicon, the song appears in the list only once and my ‘grouping’ is gone. Obviously also when syncing back from Lexicon to Rekordbox.

Is this expected behavior of Lexicon?
And are others using the same concept, but have suggestions on how I can better do this?

Lexicon only supports tracks once in a playlist so on import those double tracks are lost in the playlist. Some users use a workaround by having multiple dummy tracks for separators instead of just one.
