Keeping the search on a playlist when I return to it

In Rekordbox DJ, The search doesn't stay when I return to the playlist after clicking on other playlists.

Does this make sense?

In the tree: If I click on the "All Tracks" of my iTunes and do a search, that search doesn't stay if I click on other playlists before returning to the "All Tracks". I want to return to the "All Tracks" and have my search still there.
